Read article 'CMS observes collective phenomena in pp collisions'
When heavy nuclei collide at high energies, a novel state of hot and dense matter – the quark–gluon plasma (QGP) – is expected to form. As a region of QGP expands and cools, it disso...
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 the past few years, ho...
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 partons carry informati...
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 p17), and surprisingly...
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 nuclei at √sNN = ...

Giulia Zanderighi reviews in 2016 the book 50 Years of Quarks.
Read article '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...
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 degrees of freedom are ...

The facility features two beamlines and two experimental halls.
Read article '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...
