An important open question regarding hadronization in heavy-ion collisions is to understand the baryon enhancement at intermediate pT observed at RHIC. In this work we analyze the p/π ratio in the associated yield (pT < 5.0 GeV/c) correlated to a high-pT trigger (pT > 5.0 GeV/c) in central Pb–Pb collisions. For this analysis we used Pb–Pb data taken by the ALICE detector at a center of mass...

Inclusive Proton/pion ratios show an enhancement at intermediate transverse momentum (PT ~1.5 - 4.0 GeV/c) in central √sNN = 200 GeV Au+Au collisions compared to peripheral Au+Au and p+p collisions. This effect suggests a production mechanism, different from fragmentation, which is consistent with coalescence and recombination models. A high-ET trigger particle selects a surface-biased jet,...

We present new, data-driven analysis methods for the measurement of reconstructed jets over a broad kinematic range, in the complex environment of heavy ion collisions. We utilize simple model calculations that contain the essential features of jet reconstruction in nuclear collisions at both energies, in order to assess systematic uncertainties of the methods due to large experimental...

Jet reconstruction and jet structure variables provide important information to study the interaction between hard scattered partons and the Quark-Gluon Plasma. This talk presents the measurement of the inclusive cross-section for fully reconstructed jets in pp collisions at \sqrt{s}=2.76 TeV, which provides an essential reference for jet measurements in Pb-Pb collisions at the same...

We study the perturbative evolution of a jet via multiple gluon emissions induced by the interactions between the jet constituents and a dense QCD medium like a quark-gluon plasma. We focus on the typical medium-induced gluons emissions, for which the gluon formation time is much smaller than the overall size of the medium. We show that the typical time between two subsequent emissions is...
