Nuclear Physics News is a bimonthly journal published on behalf of the Nuclear Physics European Collaboration Committee (NuPECC), an Expert Committee of the European Science Foundation with colleagues from Europe, America and Asia.

In the last issue of Nuclear Physics News (Vol. 23, No.2, 2014), ALICE member Elena Bruna contributed to an overview of the recent results from ALICE and one  Pb-Pb event display appeared in the cover page of the same issue.

The ALICE detector has collected so far a large amount of observations in different collision systems (pp, PbPb and pPb) that yielded a large array of key measurements. In particular she discussed results from Pb-Pb collisions indicating a high degree of collectivity in the particle emission at low-intermediate transverse momentum in non-central collisions suggesting that the QPG behaves like a viscous fluid.

The heavy-flavour measurements in Pb-Pb collisions also show that the hot and very dense medium causes massive energy loss even to heavy quarks produced in initial hard scatterings, as well as the melting of quarkonia which can be recombined at the LHC energies. 

The benchmark p-Pb data has yielded a wealth of unexpected results that opened new studies in this collision system. It was also emphasized that the comparison to Pb-Pb and p-Pb collisions is a crucial aspect toward a quantitative characterization of the QGP.

ALICE is now preparing for the next run that will take place in 2015 and with more statistics available and use of different triggers we will be able to improve the measurements obtained so far.

Alice Physics Harvest

<p>Well done, let's hope that a new Alice Physics harvest collected during the coming second period of LHC running wil be equally rich. &nbsp;</p>
