Multiplicity dependence of D*+-meson production in p-Pb collisions with ALICE

  • 1. Physikalisches Institut, Ruprecht-Karls Universitaet Heidelberg (Germany)

Description

The heavy-ion programme at ALICE (A Large Ion Collider Experiment) facilitates the study of the hot, high-density state of matter formed in high-energy nuclear collisions. A key probe of this system is the production of heavy quarks, namely charm and beauty. Charm and beauty quarks are produced in the earliest stages of the collision, and experience the full evolution of the system. As well as studying the production of leptons from heavy-flavour decays, ALICE's excellent tracking, vertexing, and particle identification capabilities also allow it to fully reconstruct the hadronic decays of open-charmed D mesons. Control measurements are made in p-Pb collisions in order to disentangle experimental outcomes arising in the hot and dense medium from those occurring due to initial-state effects. One interesting measurement that can be made in this system is the production of certain particle species as a function of the overall multiplicity of charged particles. Such measurements allow us to investigate the role of multi-parton interactions in particle collisions at LHC energies, in particular when compared with similar results in pp collisions. In this talk, the ALICE measurements of D*+-meson production as a function of charged-particle multiplicity in p-Pb collisions at √(sNN)=5.02 TeV are presented, along with comparisons with D0 and D+ results in p-Pb and pp.
