From pp to Heavy-Ion Collisions at the LHC: the ALICE Experimental Programme
Karel Šafařík (CERN)
Seminar Room 3, 15:00
The physics motivation to collide heavy ions at LHC will be discussed.
The dedicated heavy-ion collision detector, ALICE, which few days ago
collected the first events from proto-proton collisions at LHC, will be
described. Its performance, estimated from the simulations and from
the analysis of cosmic-ray data, and the commissioning status will be
reported. The main part of the talk will be devoted to the physics
programme: from pp to heavy-ion collisions. At the end the result on
charged-particle pseudorapidity density in pp interactions at
sqrt(s) = 900 GeV, measured by ALICE with the data recorded
during the LHC commissioning run, will be presented.
