ALICE p-Pb test run gets media coverage

At the beginning of 2013, just before the LHC shutdown, the ALICE experiment will get another opportunity to collect exciting data with the asymmetric proton-lead collisions. These data are crucial for understanding the complexity of the lead-lead interaction in many levels and are a necessary supplement for the baseline proton-proton data.

First p=Pb collisions at LHC as "seen" with ALICE

Preceding that period, LHC performed on the 13th of September a short pilot-run, few hours of data taking, that allow the machine to optimize the setup of the injection and collision of the proton and lead beams and the experiments to be ready to collect the physics message that they carry. This was the first time that LHC was accelerating two beams of different particles and performing these asymetric collisions which are very important for the study of the physics of Quark Gluon Plasma.

Following the pilor run, data from p-Pb collisions will represent an ultimate benchmark for the already published results from Pb-Pb collisions. It will definitely allow to decouple the cold nuclear matter effects and thus will shed light to our quest for the quark-gluon plasma.

Proton lead-ion collisions seen by the ALICE detection system was one more groundbreaking achievement that made headlines across the world:
