Measurement of electrons from semi-leptonic heavy-flavour hadron decays in p-Pb collisions at √sNN=5.02 TeV with the ALICE TRD — •Martin Fleck for the ALICE collaboration — Heidelberg University, Deutschland
Heavy quarks (charm and beauty), only produced in the initial hard scattering processes, constitute an important way to probe features of the Quark-Gluon Plasma. However, suppression effects that are seen in Pb–Pb collisions in comparison to p–p results can be regarded as a property of the Quark-Gluon Plasma after non-QGP nuclear effects in the study of proton-nucleus collisions have been quantified. For this purpose the ALICE TPC and TRD were used to measure semi-leptonic decays of heavy-flavoured hadrons, where especially the TRD electron identification capability contributes to the results. The procedure of the analysis of p–Pb LHC data of 2013 is explained and first results are shown.
