Heavy-Flavour Production in Pb-Pb collisions at the LHC with ALICE
Yvonne Pachmayer (for the ALICE Collaboration)
TL;DR
This paper reports on heavy-flavour production in lead-lead collisions at the LHC, showing significant suppression and azimuthal anisotropy, indicating strong medium effects on heavy quarks.
Contribution
It provides new measurements of heavy-flavour suppression and flow in Pb-Pb collisions at 2.76 TeV using ALICE, highlighting the interaction of heavy quarks with the quark-gluon plasma.
Findings
Strong suppression of heavy-flavour yields in central collisions
Non-zero azimuthal anisotropy (v2) for D-mesons
Similar flow behavior between D-mesons and charged hadrons
Abstract
Results on open heavy-flavour production in Pb-Pb collisions at sqrt{s_NN} = 2.76 TeV measured with ALICE at the LHC are presented. The nuclear modification factors, extracted in three different channels, show a strong suppression in central collisions. The measured D-meson azimuthal anisotropy indicates a non-zero v2, which is similar to the one of charged hadrons.
