Transverse momentum distributions of charged particles in Pb–Pb collisions with ALICE at the LHC — •Julius Gronefeld for the ALICE collaboration — Research Division and ExtreMe Matter Institute, GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt — Institut für Kernphysik, Technische Universität Darmstadt
ALICE is a LHC experiment dedicated to heavy ion collisions, with the aim of understanding the physics of the hot and dense medium produced in collisions of lead ions.
Since November 2015 the LHC is running close to the designed energy, delivering collision energies of √sNN = 5 TeV per nucleon pair in the Pb–Pb collision system.
The study of inclusive charged particle production sheds light the suppression of high transverse momentum (pT) hadrons, due to parton energy loss in the medium. A common way to investigate this effect is the determination of the nuclear modification factor (RAA) given by the ratio between a pTspectrum and a pp reference spectrum scaled by the number of binary collisons.
In this talk transverse momentum distributions measured with ALICE at a collision energy of √sNN = 5 TeV in Pb–Pb collisions will be presented. Spectra and RAA will be shown in dependence on centrality. In addition the findings will be compared to current models.
