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 p_T < 50 GeV/c. With the much higher statistics of the 2017 data sets, a more precise analysis with higher p_T reach and finer p_T 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.
