Read article 'STAR helps to pin down a key phenomenon in gold collisions'
The Brookhaven National Laboratory has published new evidence indicative of a "chiral magnetic wave" rippling through quark–gluon plasma.
Read article 'First full jet measurement in Pb–Pb collisions with ALICE'
In high-energy collisions at the LHC, quarks and gluons occasionally scatter violently and produce correlated showers of particles, or “jets”. In proton–proton collisions, the rate o...
Read article 'ALICE sheds light on particle production in heavy-ion collisions'
New results from the ALICE collaboration are providing additional data to test ideas about how particles are produced out of the quark–gluon plasma (QGP) created in heavy-ion collisions at the L...
Read article 'Profiling jets with ALICE'
Scaled pT spectra of charged particles in jets for different bins of jet transverse momentum. “Jets are collimated sprays of particles.” This ubiquitous characterization used in man...
Read article 'ALICE probes the role of minijets in p–Pb collisions…'
One of the hottest topics at the LHC is the understanding of potential collective effects in proton–lead collisions, prompted by the discovery of ridge structures in angular correlations of part...
Read article 'Heavy-ion collisions: where size matters'
Results from ALICE provide insight into the size of the final state at “freeze-out” – and a window on collective behaviour.
Read article 'Cosmic particles meet the LHC at ISVHECRI'
More than 120 physicists from across the world met at CERN to discuss questions related to hadron production in cosmic-ray interactions and at accelerator experiments.
Read article 'ALICE and the flowing particle zoo'
Relativistic heavy-ion collisions produce large numbers of particles that do not move individually, but rather as an organized group, with a collective motion known as flow. Flow studies at Brookhaven...
Read article 'Quark Matter 2014: news from ALICE'
The new results shown by the ALICE collaboration at the Quark Matter 2014 conference in Darmstadt focus principally on the most recent collisions at the LHC – those of protons and lead nuclei (p...
