Read article 'ALICE zeroes in on cold-matter effects'
Measuring the production cross-section of charm hadrons in proton–proton collisions provides an important test of perturbative quantum chromodynamics (QCD). In proton–nucleus c...
Read article 'ALICE prepares for high-luminosity LHC'
The LHC is preparing for a major high-luminosity upgrade (HL-LHC) with the objective to increase the instantaneous luminosity to around 2 × 1035 cm–2 s–1 for proton–...
Read article 'ALICE explores shear viscosity in QCD matter'
One of the key goals in exploring the properties of QCD matter is to pin down the temperature dependence of the shear-viscosity to entropy-density ratio (η/s). In the limit of...
Read article 'ALICE pinpoints J/ψ regeneration'
The ALICE Collaboration has measured with improved precision the production of J/ψ mesons in collisions of lead nuclei at the highest LHC energy, confirming the role of the “reg...
Read article 'ALICE measures higher-flow harmonics'
In a collision between two nuclei that exhibits a large impact parameter, the initial spatial anisotropy of the overlap region was conjectured to be smooth and almond shaped. In th...
Read article 'ALICE separates hot and cold nuclear effects'
In the early stages of a high-energy collision, high-pT partons can be created, before producing sprays of hadrons that are measured experimentally as jets. Not only do high-pT par...
Read article 'ALICE probes small-system dynamics with charm production at the LHC'
The first p–Pb data-taking campaign at the LHC was undertaken as a test of the initial state of heavy-ion collisions (CERN Courier March 2014 p17 and CERN Courier October 2013 p1...
Read article 'ALICE finds a new source of charmonium'
The ALICE collaboration has studied the production of charmonium – bound states of charm and anti-charm quarks – in hadronic as well as in ultra-peripheral collisions of lead n...
Read article '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 deg...
Read article 'ALICE looks to the skies (part II)'
The ALICE experiment, designed for the LHC heavy-ion programme, is particularly well-suited for the detection and study of very high-energy cosmic events. The apparatus is located ...
