### ALICE investigates ‘snowballs in hell’

Résumé L’omelette norvégienne d’ALICE Il n’y a pas uniquement des hadrons ordinaires dans les débris des ” boules de feu ” produites par les collision...

### 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...

### 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...

### 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...

### 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...

### 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...

### 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...

### ALICE: is cold nuclear matter really cold?

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...

### A new focus on forward muons for the ALICE upgrade programme

The ALICE experiment, with its state-of-the-art detection systems, produced a wealth of results during Run 1 of the LHC (2009–2013) – driving a new impetus in the field of heavy-ion collisions. W...

### ALICE: on the trail of a new state of matter

Résumé ALICE : sur les traces d’un nouvel état de la matière Après deux périodes de collisions plomb-plomb au LHC, complétées par des campagnes de collisi...
