The Brookhaven National Laboratory has published new evidence indicative of a "chiral magnetic wave" rippling through quark–gluon plasma.
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...
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...
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...
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...
Results from ALICE provide insight into the size of the final state at “freeze-out” – and a window on collective behaviour.
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.
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...
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...
Résumé ALICE : la matière nucléaire froide est-elle vraiment froide ? En septembre 2012, pour la première fois, des collisions proton-plomb ont eu lieu au LHC ; une exploitati...
