Charged particle production as a function of multiplicity measured with ALICE at the LHC — •Mario Krüger for the ALICE collaboration — Institut für Kernphysik Frankfurt

Heavy-ion collisions at the Large Hadron Collider facilitate the study of the Quark-Gluon-Plasma in the laboratory. Complementary measurements of smaller collision systems have shown that already for p–p collisions signs of collectivity can be observed. The great challenge for modern Monte-Carlo event generators is to describe particle production in a consistent way for all of the collision systems.

One sensitive observable to probe the particle production mechanisms implemented in these models is the correlation between transverse momentum spectra and event multiplicity. In this talk, we report the ALICE measurement of unidentified charged-particle pT spectra obtained using a 2d-unfolding technique. We present derived quantities of these spectra and compare different collision systems and energies.
