Measurements of heavy-flavour production in p-Pb collisions with ALICE

TL;DR

This paper reports on measurements of heavy-flavour particle production in proton-lead collisions at 5.02 TeV using ALICE, focusing on nuclear modification factors and production dependencies to understand nuclear effects.

Contribution

It provides new measurements of open charm and beauty production, including nuclear modification factors and their dependence on centrality and multiplicity in p-Pb collisions.

Findings

Nuclear modification factor $R_{pPb}$ for open charm and beauty was measured.

D-meson production shows dependence on collision centrality and multiplicity.

Results contribute to understanding nuclear effects on heavy-flavour production.

Abstract

The production of open heavy-flavour particles was studied in p-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02$ TeV using the ALICE detector. Three separate observables were used: the hadronic decays of D mesons at mid-rapidity, and semileptonic decays of heavy-flavour hadrons to electrons and muons at mid-rapidity and forward rapidity, respectively. The most recent ALICE measurements of the nuclear modification factor, $R_\mathrm{pPb}$, of open charm and beauty are reported, along with the centrality and multiplicity dependence of D-meson production in p-Pb collisions.
