Read article 'First jet measurements with ALICE'
When quarks and gluons (partons) in opposing beams at high-energy hadron colliders meet they can scatter violently to produce correlated showers of particles, or “jets”. In proton–pr...
Read article 'ALICE looks to the future'
After more than three years of highly successful operation, the ALICE detector is about to undergo a major programme of consolidation and upgrade during the Long Shutdown 1 (LS1) of CERN’s ac...
Read article 'ALICE and ATLAS find intriguing ‘double ridge’ in proton–lead collisions'
In analysing data from last year’s test run with proton–lead collisions in the LHC, the ALICE collaboration, followed almost immediately and independently by the ATLAS collaboration, have ...
Read article 'ALICE takes new directions in charm-suppression studies'
Using data from the second high-statistics lead–lead (PbPb) run of the LHC, which took place in 2011, the ALICE experiment is taking new directions in studying the interaction of charm quarks wi...
Read article 'ALICE takes a first look at diffraction'
Diffractive processes represent more than 25% of the cross-section for inelastic proton–proton collisions at the LHC. So, it is only natural that the ALICE collaboration is interested in a field...
Read article 'Particle identification in ALICE boosts QGP studies'
Under extreme conditions of temperature and/or density, hadronic matter “melts” into a plasma of free quarks and gluons – the so-called quark–gluon plasma (QGP). To create these condit...
Read article 'ALICE tracks charm energy loss in the QGP'
The first direct observation of the suppression of charmed mesons at high transverse-momentum in head-on nucleus–nucleus collisions indicates that charm quarks suffer a strong loss of energy in&...
