Brookhaven role to focus on technology transfer

Particle physicist David Asner has been appointed deputy associate laboratory director for strategic program development at Brookhaven National Laboratory (BNL), a new role focused on growing Brookhaven’s nuclear and particle physics programme in directions outside its traditional areas.

Asner, a former spokesperson of the CLEO collaboration at Cornell and leader of the US participation in Belle at KEK, has also been appointed head of BNL’s instrumentation division, succeeding Graham Smith. A focus of the strategic BNL role is to identify opportunities for technology transfer and commercialisation in areas such as national security, space science and materials science.

DUNE elects co-spokesperson

Stefan Söldner-Rembold of the University of Manchester in the UK has been elected co-spokesperson of the international Deep Underground Neutrino Experiment (DUNE) collaboration, beginning 1 April, succeeding Mark Thomson (CERN Courier March 2018 p41).

DUNE will use two neutrino detectors placed in an intense neutrino beam produced at Fermilab to measure CP violation in neutrino interactions. Söldner-Rembold is a former spokesperson of the D0 experiment at Fermilab, where he worked on searches for the Higgs boson. He is a member of the MicroBooNE and SBND collaborations at Fermilab’s short-baseline neutrino programme, and also of the SuperNEMO and IceCube-GEN2 collaborations.

Carlin takes the helm at CMS experiment

Roberto Carlin of the INFN and University of Padova in Italy has been elected spokesperson of the CMS experiment for a two-year term beginning in September, taking over from current spokesperson Joel Butler.

Carlin, a longstanding CMS collaborator, studied physics at the University of Padova and completed his thesis on the PS170 experiment at CERN in 1989. Prior to joining CMS in 2005 he worked on ZEUS at HERA, DESY. He is currently deputy CMS spokesperson and has also played important roles in the CMS muon drift-tube detector and trigger.

Alfvén Prize for cosmic acceleration

The plasma physics division of the European Physical Society has awarded the 2018 Hannes Alfvén Prize to Tony Bell of the University of Oxford for his seminal contributions to cosmic particle acceleration.

Bell, a theoretical plasma physicist, has opened up new research fields in both astrophysical and laboratory plasmas. He also played a leading role in the development of what is now the standard model of astrophysical particle acceleration and cosmic-ray origins and has been one of the main players over three decades in developing the understanding of electron transport in laser-produced plasmas.

Five young researchers win ATLAS thesis prize

On 22 February the ATLAS collaboration presented the latest winners of its annual thesis awards. Five winners were selected from a total of 31 nominations spanning all areas of ATLAS physics, from detector development and operations to software and performance studies and physics analyses: Pierfrancesco Butti (Nikhef), Johanna Gramling (University of Geneva), Oleh Kivernyk (University of Paris-Saclay), Philip Sommer (Albert Ludwigs University of Freiburg) and Markus Zinser (Johannes Gutenberg University Mainz). PhD students make up almost a fifth of the ATLAS collaboration’s 5500 members and contribute greatly to all areas of the experiment while learning valuable skills for their degrees.

Big science meets industry in Copenhagen

Big science equals big business, whether it is manufacturing giant superconducting magnets for particle colliders or perfecting mirror coatings for space telescopes. The Big Science Business Forum (BSBF), held in Copenhagen, Denmark, on 26–28 February, saw more than 1000 delegates from more than 500 companies and organisations spanning 30 countries discuss opportunities in the current big-science landscape.

Nine of the world’s largest research facilities – CERN, EMBL, ESA, ESO, ESRF, ESS, European XFEL, F4E and ILL – offered insights into procurement opportunities and orders totalling more than €12 billion for European companies in the coming years. These range from advisory engineering work and architectural tasks to advanced technical equipment, construction projects and radiation-resistant materials. A further nine organisations also joined the conference programme: ALBA, DESY, ELI-NP, ENEA, FAIR, MAX IV, SCK•CEN – MYRRHA, PSI and SKA, thereby gathering 18 of the world’s most advanced big-science organisations under one roof.

The big-science market is currently fragmented by the varying quality standards and procurement procedures of the different laboratories, delegates heard. BSBF aspired to offer a space to discuss the entry challenges for businesses and suppliers – including small- and medium-sized enterprises – who can be valuable business partners for big-science projects.

“The vision behind BSBF is to provide an important stepping stone towards establishing a stronger, more transparent and efficient big-science market in Europe and we hope that this will be the first of a series of BSBFs in different European cities,” said Agnete Gersing of the Danish ministry for higher education and science during the opening address.

Around 700 one-to-one business meetings took place, and delegates also visited the European Spallation Source and MAX IV facility just across the border in Lund, Sweden. Parallel sessions covered big science as a business area, addressing topics such as the investment potential and best practices of Europe’s big-science market.

“Much of the most advanced research takes place at big-science facilities, and their need for high-tech solutions provides great innovation and growth opportunities for private companies,” said Danish minister for higher education and science, Søren Pind.

Nanotechnology: from materials to science

Aiming to bring companies and researchers active in nanotechnology together with experts from other research fields, such as high-energy physics or medical science, the CERN-fostered High-Energy Physics Technology Transfer Network (HEPTech) organised an academia–industry matching event on 15–16 February at Charles University in Prague. The forum was part of the HEPTech’s programme in nanotechnology and attracted about 60 participants from 11 European countries. It was co-organised by participants of the EU project ACCELERATE, which aims to support the long-term sustainability of large-scale research infrastructures.

Many conventional techniques and methods for nano-scale characterisation and analysis have reached their limit, requiring further development. Research in high-energy physics has allowed the development of accelerator and detector technology that can be applied in other research fields, and nanotechnology is among them.

The Prague event discussed several examples of where particle physics can impact nano-analysis and characterisation, particularly in biological and pharmacological environments. Other examples included X-ray imaging techniques for use in the PETRA III light source to visualise 3D microscopic structures with resolutions down to below 1 μm, while Elettra Sincrotrone Trieste focused on the capabilities for operando characterisation of advanced batteries and fuel cells using X-ray absorption spectroscopy and X-ray photoelectron spectroscopy. The Ruđer Bošković Institute in Croatia shared its experience in the production and analysis of nanostructures using ion beams in the MeV energy range.

• HEPTech is mandated by and reports to the CERN Council and its programme is aligned with the directives of the European Strategy for Particle Physics.

Beauty workshop highlights CERN–China links

At first sight, the LHCb experiment at CERN and the BESIII experiment at the Institute of High Energy Physics (IHEP) in Beijing are different experiments with little in common. The former operates in the fierce environment of 13 TeV proton–proton collisions of the LHC, whereas BESIII collects data from the BEPC accelerator, an electron–positron collider operating at energies of 3–4 GeV. Yet both experiments have been built for flavour physics, which is the study of the properties and decays of hadrons containing a heavy quark (beauty or charm in the case of LHCb; charm in the case of BESIII). As such, there are many topics of common interest between LHCb and BESIII. Moreover, measurements made at one collider can provide useful and essential input to the physics programme at the other.

On 8–9 February a workshop took place at IHEP to explore these synergies – the first such joint meeting between LHCb and BESIII – involving around 70 representatives from the experiments in addition to several invited theorists.

CP violation, which probes the difference in behaviour between matter and antimatter, is a central area of study for LHCb and a clear example of the benefits of closer collaboration with BESIII. Many CP-violation measurements involve decay processes where a beauty hadron decays into a charm meson, which itself subsequently decays. A clean interpretation of the results requires a complete understanding of the characteristics of the charm decay, and this can be provided by BESIII. Furthermore, many LHCb analyses targeted at testing lepton universality, a very hot topic at present (see Beauty quarks test lepton universality), can be improved by a more complete survey of charm decays that provide potential backgrounds to the signal samples. BESIII is an ideal experiment for performing such a survey.

These and related topics were the subject of lively discussions at the meeting, with attention devoted to both the potential of the current BESIII data and the future running plans of the Beijing experiment. It was concluded that future such events should be organised, and that the two collaborations should work closely together. This will enable us to obtain the best possible sensitivity to the key observables in flavour physics and to explore the full potential of this unique synergy between two major high-energy physics facilities.

Training young researchers in South-East Europe

The Southeastern European Network in Mathematical and Theoretical Physics (SEENET-MTP) organises scientific training and research activities in the Balkan and neighbouring regions. Since it was founded in 2003, the network has promoted the exchange of students and researchers, and contributed to institutional capacity building in physics and mathematics.

In January 2015, with the support of CERN, SEENET-MTP launched a joint PhD training programme aimed at students from southeastern European countries. The main part of the programme was designed to be a series of intense, one-week schools for PhD students, advanced masters students and young postdocs in high-energy physics and related fields. Each school included lectures followed by appropriate exercises, and the programme became part of a general agreement of cooperation between CERN and SEENET-MTP signed in February 2017.

The fourth school, New Trends in High Energy Theory, was held in Sofia, Bulgaria, from 15–22 October 2017, and the main seminar topics were string theory and black holes, with a focus on holography. The opening course, by Timo Weigand of CERN, gave a comprehensive introduction to string theory, starting from the world-sheet formulation of the bosonic and superstrings, and recalling the main properties of D-branes and the low-energy effective supergravity. Other guest lecturers were Atish Dabholkar (ICTP, Trieste), Anastasios Petkou (AU, Thessaloniki), Veselin Filev (DIAS, Dublin) and Nikolay Bobev (KU Leuven, Belgium), who focused on the systematic introduction of the AdS/CFT correspondence.

The 2017 school was organised by the faculty of physics at Sofia University, and moderated by SEENET-MTP president Dumitru Vulcanov (West University of Timisoara) and executive director Goran Djordjevic (University of Niš). A total of 26 participants from six SEENET-MTP countries and Belgium attended. Besides CERN, these activities were supported by the ICTP, the European Physical Society, Sofia University and SEENET-MTP. The next school, High Energy and Particle Physics: Theory and Phenomenology, will be held in Niš, Serbia, on 3–10 June 2018, followed by a workshop on field theory and the early universe, and other events to mark 15 years of the network.
