Transverse momentum distributions of charged particles and nuclear modification factor in Xe-Xe collisions with ALICE at the LHC — •Michael Habib for the ALICE collaboration — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Planckstraße 1, 64291 Darmstadt
The study of charged particle production indicates a suppression of hadrons at high transverse momentum ( pT ) when compared to pp collisions, as a consequence of parton energy loss in the medium.
In October 2017, a 6 hour pilot run with with colliding Xenon beams opened up the opportunity to study system-size effects when compared to the usual operation with Lead beams.
In this talk we present transverse momentum spectra and nuclear modification factors ( RAA ) in Xe-Xe collisions at √sNN = 5.44 TeV for nine centrality classes. Comparison to results in Pb-Pb collisions at √sNN = 5.02 TeV are given.
