Transverse momentum spectra of charged particles in pp collisions at s = 5.02 TeV — •Youssef El Mard Bouziani for the ALICE collaboration — Institut für Kernphysik, Goethe-Universität Frankfurt

The ALICE experiment at the LHC is designed to study the properties of the Quark-Gluon Plasma which is believed to be created in heavy-ion collisions. To distinguish medium effects from QCD vacuum effects a reference measurement of charge particle production in pp collisions is compared to the one in Pb-Pb collisions by means of the nuclear modification factor.

In previous measurements, charge particle production in pp collisions at √s = 5.02 TeV, recorded in 2015, was limited to a transverse momentum pT < 50 GeV/c. With the much higher statistics of the 2017 data sets, a more precise analysis with higher pT reach and finer pT binning is possible.

In this poster, we present an analysis of the cross section of charge particle production in pp collisions at √s = 5.02 TeV based on these data sets.
