ALICE Highlights at Hard Probes 2015

A review of selected measurements by the ALICE Collaboration discussed at the Hard Probes 2015 conference is given. The production of J/ ψ as well as long-range two particle correlations in proton-lead collisions at s=5.02 TeV are discussed. The parton energy loss in a quark-gluon plasma created in Pb–Pb collisions at s=2.76 TeV is discussed based on the measurements of semi-inclusive charged particle jets correlated with a high- pT hadron, the nuclear modification factor ( R AA ) for identified hadrons and D-mesons. Moreover, D-meson R AA is compared with the R AA of non-prompt J/ ψ measured by the CMS Collaboration showing that the parton energy loss depends on the mass of the parton. In addition, further studies of J/ ψ production in peripheral nuclear collisions show an excess of low momenta mesons beyond the expectation for purely hadronic production.
