Inflation and String Theory

By D Baumann and L McAllister Cambridge University Press

6c4d6091cca3cf45ef4954fe9f5aa09e0d40f9be_BF2000-2000

This complete and accessible text, written by two of the leading researchers in the field, provides a modern treatment of inflationary cosmology and its connection to string theory and elementary particle theory.

The past two decades of advances in observational cosmology have brought about a revolution in our understanding of the universe. In particular, deeper studies of the cosmic microwave background have revealed strong evidence for a period of inflationary expansion in the very early universe. At the same time, new developments in string theory have led to a better understanding of inflation in a framework that unifies quantum mechanics and general relativity.

After a brief introduction about observations in favour of the inflationary hypothesis, the volume provides an overview of effective field theory, string theory, and string compactifications. Finally, several classes of models of inflation in string theory are examined in detail.

The background material in geometry and cosmological perturbation theory included in the appendices makes the book self-contained and accessible not only to experienced researchers, but also to graduate students and readers who are new to the field.

Nuclear and Particle Physics

By Claude Amsler
IOP Publishing

41wkxhUuQ3L._SY264_BO1,204,203,200_QL40_ML2_

This textbook provides an introductory course on nuclear and particle physics for undergraduate and early graduate students. It originated from a series of lectures given at the Physics Institute of the University of Zurich by the author. The subjects are presented following their historical development. The explanations are experimentally and phenomenologically orientated, and often make use of intuitive arguments. In addition, many concepts and phenomena are derived with inductive rather than deductive thinking.

Originally published in German, this new version in English has been enriched with several modern topics, such as the Higgs boson, updates on neutrinos, the top quark and bottom-quark physics.

Supersymmetric Field Theories: Geometric Structures and Dualities

By Sergio Cecotti
Cambridge University Press

51nOLEW2zkL._SY291_BO1,204,203,200_QL40_ML2_

An unconventional and elegant geometrical approach is adopted in this book to explain supersymmetric field theories, and describe intuitive methods for understanding the logic underlying such concepts. Aimed at graduate students and researchers, the collection of lectures provides an advanced course in supergravity and supersymmetry, which requires knowledge of the basic concepts and fundamental tools of these fields. The author shows how complex results and formulae obtained from the more classical approaches to SUSY can be simplified dramatically when translated to a geometric setting.

Covering a wide range of topics and offering rigorous, in-depth explanations, this text would be an extremely valuable resource for theoretical physicists.

World Scientific

particle-and-astroparticle-physics-gravitation-and-cosmology-predictions-observations-and-new-projects-proceedings-of-the-xxx-th-international-workshop-on-high-energy-physics

The most interesting talks delivered at the XXXth International Workshop on High Energy Physics, held in Protvino, Russia, in June 2014, are collected in this volume, along with the minutes of the six panel discussions. As the full title suggests, this conference not only focused on high-energy physics, but addressed a wide range of fundamental issues of modern particle and astroparticle physics, gravitation and cosmology.

The major subjects presented included the discovery and interpretation of the Brout–Englert–Higgs boson at the LHC, heavy-quark physics, quark–gluon plasma studies, diffractive scattering at high energies, neutrino oscillations, and theoretical interpretations of cosmological data on the evolution of the universe.

The panel discussions, in turn, highlighted difficult points in the various domains of modern physics, and identified possible research paths.

General Relativity and Gravitation: A Centennial Perspective

By A Ashtekar et al (eds)
Cambridge University Press

9781107037311

On the occasion of the centennial of Einstein’s discovery of general relativity, the International Society on General Relativity and Gravitation commissioned a team of leading international researchers to write about the advances that have occurred in all of the branches of physics during the last three decades. Through 12 comprehensive chapters, the volume gives an overview of key topics in relativistic astrophysics, cosmology and gravitational-wave theories, as well as mathematics and computational science. The book in intended both for beginners, who could use it as an introduction to the entire field, and for more advanced researchers, especially if they are interested in subjects that are outside of their field of expertise. Organised in four parts, each of about five chapters, the book guides the reader on a journey from the triumph of Einstein’s theory of relativity through the phenomenon of gravitational waves, to quantum gravity.

QCD and Heavy Quarks: In Memoriam Nikolai Uraltsev

By I I Bigi, P Gambino and T Mannel (eds)
World Scientific

41wmKZHvshL._SX328_BO1,204,203,200_

The book collects together articles on QCD and heavy-quark physics written in memory of Nikolai Uraltsev, who passed away unexpectedly in February 2013. Uraltsev was an excellent theorist with acute intuition, who dedicated his career to the study of phenomenological particle physics, in particular quantum chromodynamics and its non-perturbative properties. He is also considered one of the fathers of heavy-quark expansion. By writing this book, Uraltsev’s closest colleagues and friends intended to honour his groundbreaking work, as well as give testimonies of their personal relationships with him.

The text gives an overview of some aspects of QCD, including CP violation in hadronic processes and hadronic matrix elements in weak decays. Three selected works by Uraltsev are also reproduced in the appendix.

Quantum Field Theory and the Standard Model

By Matthew D Schwartz
Cambridge University Press
Also available at the CERN bookshop

71DqLQg8mML

Providing a comprehensive and modern introduction to quantum field theory, this textbook covers the development of particle physics from its foundations to the recent discovery of the Brout–Englert–Higgs boson. Based on a course taught by the author at Harvard University for many years, the text starts from the principle that quantum field theory (QFT) is primarily a theory of physics and, as such, it provides a set of tools for performing practical calculations. The book develops field theory, quantum electrodynamics, renormalisation and the Standard Model, including modern approaches and state-of-the-art calculation techniques.

With a combination of intuitive explanations of abstract concepts, experimental data and mathematical rigour, the author makes the subject accessible to students with different backgrounds and interests.

Gaseous Radiation Detectors: Fundamentals and Applications (Cambridge Monographs on Particle Physics, Nuclear Physics and Cosmology)

By Fabio Sauli
Cambridge University Press
Also available at the CERN bookshop

CCboo1_10_15

In the last few decades, fast revolutionary developments have taken place in the field of gaseous detectors. At the start of the 1970s, multiwire proportional chambers were invented. These detectors and their descendants (drift chambers, time-projection chambers, ring-imaging Cherenkov detectors, etc) rapidly replaced cloud and bubble chambers, as well as spark counters, in many high-energy physics experiments. At the end of the last century, resistive-plate chambers and micropattern detectors were introduced, which opened up new avenues in applications.

Ironically, for a long time, no books had been published on gaseous detectors and their fast evolution. For this reason, in spite of thousands of scientific publications covering the rapid and exciting developments in the field of gaseous detectors, no simple and analytical description has been made available for a wide audience of non-professionals, including, for example, students.

Suddenly “an explosion” took place: several books dedicated to modern gaseous detectors and their applications appeared on the market, almost all at the same time.

Sauli’s book is certainly one of the best of these. The author, a leading figure in the field, has succeeded in writing a remarkable and charming book, which I strongly recommend to anyone interested in learning about recent progress, open questions and future perspectives of gaseous detectors. Throughout its 490 pages, it offers a broad coverage of the subject.

The first five chapters focus on fundamentals: the interaction of charged particles and photons with matter, the drift and diffusion of electrons and ions, and avalanche multiplications. This first part of the book offers a refreshing mix of basic facts and up-to-date research, but avoids giving too much space to formulas and complicated mathematics, so non-specialists can also gain from the reading.

The remaining eight chapters are dedicated to specific detectors, from single-wire proportional counters to state-of-the-art micro-pattern gaseous detectors. This latter part of the book gives exhaustive detail and describes the design and operational features, including signal development, time and position resolutions, and other important characteristics. The last chapter deals with degeneracy and ageing – serious problems that detectors can experience if the gas composition and construction materials are not chosen carefully.

This fascinating book is easy to read, so it is suitable for everyone, and in particular, I believe, for young people. I was especially impressed by the care with which the author prepared many figures, which in some cases include details that I have not seen in previous texts of this kind. The high-quality figures and photographs contribute significantly to making this book well worth reading. In my opinion, it is not only remarkably complementary to other recently published monographs, but it can also serve as a main textbook for those who are new to the field.

The only omission I have observed in this otherwise wide-ranging and well-researched book, is the lack of discussion on secondary processes and ion back flows, which are very important in the operation of some modern photosensitive detectors, including, for example, ALICE and COMPASS ring-imaging detectors.

There could be a few other improvements in a future edition. For instance, it would be useful to expand the description of the growing applications of gaseous detectors, especially resistive-plate chambers and micropattern detectors.

All in all, this is a highly recommendable book, which provides an interesting guided tour from the past to present day of gaseous detectors and the physics behind their operation.

Our Courier

The CERN Courier is not exclusively CERN’s. Its subtitle “International Journal of High-Energy Physics” stands as a friendly warning to all those readers who might otherwise think it is an official mouthpiece of the CERN laboratory. As the new editor, I share my predecessor’s vision (and hope) of producing a magazine that will interest and stimulate the entire high-energy physics community across the world.

Over the last decade, the community has expanded to encompass physicists from many different areas – not just accelerator physics and not just from CERN. Today, the high-energy frontier is being explored not only by particle physicists but also by astrophysicists, cosmologists, astroparticle physicists and neutrino physicists. We use accelerators such as the unique LHC, but also satellites and detectors installed on the International Space Station. The hard-won results of physicists worldwide are increasingly a collaborative effort, where the boundaries between the various sub-disciplines have faded to nothing.

Our ambition must be to follow the natural evolution of the high-energy physics community and continue to be its magazine for years to come. How will we achieve this? You might have already noticed a few small changes in the November issue. A first visible change is this “Viewpoint”. Up until the October issue, it could be found at the end of the issue. Now it has been placed at the start, and its role has changed from that of an opinion piece to being the opening article intended to grab the reader’s attention. Is it working? Are you reading it? Please let me know. Although this is probably the first time that we have appealed for feedback directly in these pages, the fact that the CERN Courier is open to contributions and feedback from the wider community is far from new. From when the magazine was first published online, the “Contact us” webpage has stated the following, in French and English: “CERN Courier welcomes contributions from the international high-energy physics community. These can be written in English or French, and will be published in the same language. If you have a suggestion for an article, please send your proposal to the editor.”

In other words, for many years we have been eager to hear from you. And, indeed, you have communicated with us and given your feedback, and we have published your work, your professional ambitions, and your points of view. We have been part of your life and you have been part of ours. Many thanks for that. And what does the future hold? The CERN Courier will continue to bring you its authoritative insight into scientific information; it will continue to keep you abreast of developments at CERN and other laboratories worldwide; it will continue to bring you the very best images and, where possible, the very best video clips (yes, purely “sciency” videos, produced exclusively for the CERN Courier, see “A close look at the world’s largest astronomical project” of this issue) and other multimedia material.

Being an editor of a (still) printed publication in 2015 is no easy task. Out there in the world, information flows fast. Here, at the CERN Courier, we still take time to do things properly. As Christine Sutton, the previous editor, said in her “Viewpoint” in the November issue, our ambition is to take you “behind the headlines” and bring you the real protagonists with their full stories. The CERN Courier has the space, and that space is for you.

Let me take this opportunity to thank all of our regular contributors. Most of them have collaborated with us on a voluntary basis for many years and are the backbone of the magazine. Their profiles, together with that of our new “Bookshelf” editor, Virginia Greco, are available at preview-courier.web.cern.ch/cws/our-team. Obviously, the magazine would not exist without the hundreds of contributors worldwide who send us their texts, be they a feature article or a short piece for “Faces & Places”. A big thank you to everyone.

The CERN Courier adventure continues.

Qu’est-ce que le boson de Higgs mange en hiver et autres détails essentiels

By Pauline Gagnon
MultiMondes
Hardback: €29
E-book: €19
Also available at the CERN bookshop

CCboo1_09_15

Pauline Gagnon est bien connue dans la communauté des expérimentateurs au LHC car, en plus de sa contribution à l’expérience ATLAS, elle a été membre du groupe de communication du CERN de 2011 à 2014 et sur le blog Quantum Diaries elle a couvert de nombreux évènements récents liés à l’activité scientifique du laboratoire.

Le titre de son livre rédigé en français, ” Qu’est ce que le Boson de Higgs mange en hiver ” est quelque peu trompeur, car les propos de l’auteur vont bien au delà de la description du mécanisme de Brout-Englert & Higgs et de la découverte expérimentale du boson de Higgs en 2012. Son livre offre non seulement une vue d’ensemble de la physique étudiée dans les expériences au LHC, du complexe d’accélérateurs et de détecteurs réalisés pour cette recherche et des méthodes statistiques employées pour la découverte du Boson de Higgs, mais inclut aussi un chapitre qui décrit l’organisation originale (et probablement unique) des grandes collaborations internationales en physique des hautes énergies ainsi qu’un chapitre sur les transferts de technologie et de connaissance de notre domaine vers le monde économique et le grand public.

Le livre décrit aussi les liens qui relient la physique des hautes énergies à l’astrophysique, avec un chapitre consacré aux évidences expérimentales qui ont amené à augurer de l’existence de la matière noire, et à une comparaison entre le potentiel de découverte de celle-ci par des expériences sur et hors accélérateurs. Un autre chapitre est consacré à la super-symétrie, la théorie actuellement la plus populaire au delà du modèle standard pour répondre aux questions que celui-ci ne peut résoudre, et aux défis qui attendent les expériences du LHC dans les prochaines années. Le livre se termine par la discussion d’un thème qui est quelque peu déconnecté mais cher au cœur de l’auteur, à savoir la question de la diversité (en particulier l’emploi des femmes) dans le monde de la recherche scientifique.

Le livre n’est pas destiné aux spécialistes mais cible le grand public. A cette fin, l’auteur a banni toute formule mathématique et utilise souvent des analogies pour introduire les différents concepts. Les parties plus complexes ou plus détaillées sont incluses dans des encarts séparés que le lecteur peut éventuellement sauter. Dans le même esprit, chaque chapitre se termine par un résumé d’une page environ qui permet une lecture abrégée du point traité, quitte à y revenir plus tard. Le style est simple et direct, avec souvent une pointe d’humour. Le discours n’est cependant pas superficiel, et il me semble que le livre s’adresse tout de même à des lecteurs avec une certaine connaissance scientifique de base, par exemple des jeunes étudiants qui veulent comprendre l’intérêt et les buts de la recherche en physique des particules.
