Multiplicity dependent charged particle pT spectra with ALICE at the LHC — •Mario Krüger — Institut für Kernphysik, Goethe-Universität Frankfurt
The study of the Quark-Gluon Plasma created in ultrarelativistic heavy-ion collisions at the CERN-LHC is complemented by reference measurements in proton-lead (p–Pb) and proton-proton (pp) collisions, where the effects of multiple-parton interactions and hadronization beyond independent string fragmentation can be investigated.
In this talk, we present an unfolding procedure based on the iterative D’Agostini method to reconstruct the correlation between transverse momentum ( pT ) spectra of charged particles and the corresponding charged-particle multiplicities Nch. The unfolded spectra are presented in single multiplicity (Δ Nch = 1) bins and are used to derive moments of the pT distributions for a variety of energies and system sizes.
