Measurement of heavy-flavour decay muon production at forward rapidity in pp and Pb-Pb collisions at sqrt(s_NN)=2.76 TeV with the ALICE experiment

TL;DR

This paper reports on measurements of heavy-flavour decay muons at forward rapidity in proton-proton and lead-lead collisions at 2.76 TeV, providing insights into quark-gluon plasma effects and heavy-flavour production.

Contribution

It presents the first $p_T$-differential cross-sections in pp collisions and nuclear modification factors in Pb-Pb collisions at this energy.

Findings

Heavy-flavour decay muons are measured at forward rapidity.

Nuclear modification factors indicate suppression in Pb-Pb collisions.

Results improve understanding of quark-gluon plasma effects.

Abstract

The ALICE experiment measured the heavy-flavour production in the semi-muonic decay channel at forward rapidities ($2.5<y<4$) in pp and Pb--Pb collisions at $\sqrt{s_{{NN}}} = 2.76$ TeV. We report on the first results on the $p_{\rm T}$-differential cross-sections in pp collisions as well as on the nuclear modification factors as a function of the transverse momentum and centrality.
