Anisotropic flow in Run 2
Exploiting the data collected during November 2015 with Pb–Pb collisions at the record-breaking energy of √sNN = 5.02 TeV, ALICE measured for the first time the anisotropic flow of charged part...
ALICE selects gas electron multipliers for its new TPC
The ALICE experiment is devoted to the study of strongly interacting matter, where temperatures are sufficiently high to overcome hadronic confinement, and the effective degrees of freedom are ...
Neutrons in full flight at CERN’s n_TOF facility
Accurate knowledge of the interaction probability of neutrons with nuclei is a key parameter in many fields of research. At CERN, pulsed bunches from the Proton Synchrotron (PS) hit the spallat...
Jet ν2 measurements with ALICE
High-energy scattering of partons (quarks and gluons) produces collimated cones of particles called jets, the production rate of which can be calculated using perturbative QCD techniques. In heavy-ion...
Manufacturing and delivery of components for the new heavy-ion synchrotron SIS100 at FAIR has begun
The international Facility for Antiproton and Ion Research in Europe (FAIR) (CERN Courier May 2007 p23) is currently under construction at GSI, in Darmstadt, Germany. The FAIR accelerators will delive...
Exploring the nature of the proposed magic number N = 32
Magic numbers appear in nuclei in which protons or neutrons completely fill a shell. The existence of magic numbers to explain certain regularities observed in nuclei was discovered in 1949 independen...
Fixed-target and heavy-ion physics with LHCb
Beyond its rich programme in flavour physics based on proton–proton collisions, LHCb opened the door in 2015 to a new domain of physics exploration related to cosmic-ray and heavy-ion physics. D...
A new chapter opens with more Pb–Pb collisions for a precision study of hot and dense QCD matter
After the restart of the LHC physics programme in June 2015 with world-record proton– proton collisions at √s = 13 TeV, nuclear beams reappeared in the LHC tunnel in Novembe...
LHCb measures the effective double parton scattering cross-section with unprecedented precision
In high-energy hadron–hadron collisions, each incoming hadron behaves as a loosely bound system of massless partons – quarks, antiquarks and gluons. The interaction of incoming hadrons is describe...
ATLAS observes long-range elliptic anisotropies in √s = 13 and 2.76 TeV pp collisions
Measurements of two-particle angular correlations in proton–proton (pp) collisions at the LHC have shown a feature commonly called the “ridge”: an enhancement in production of particle p...
