Trigger particle correlations in the first collisions at ALICE

  • 1. Institut fuer Kernphysik, Frankfurt (Germany)

Description

Trigger particle correlations can provide interesting insights into jet physics. These correlations can be used in pp collisions to study jet fragmentation which is not calculable in pQCD. The angular and transverse momentum, pT, distributions of the associated particles are of particular interest in this study. Trigger particle correlations in pp collisions can also be used as a reference for heavy-ion collisions. In previous experiments, these correlations have shown medium modification in heavy-ion collisions relative to pp collisions. In ALICE trigger particle correlations can be done at much higher pT then has been done at SPS and RHIC due to the greatly increased cross section for high energy jets at the LHC. Results will be shown for simulated pp collisions at LHC energies from the PYTHIA event generator. These events have been passed though a geometrical model for the ALICE detector and reconstructed by the ALICE reconstruction software. It can be demonstrated that trigger particle correlations can be performed with triggers of pT∼10 GeV/c with one day of data taking.
