Description

Charm and bottom quarks have been proposed as probes to study partonic matter produced in high-energy heavy-ion collisions. The detailed understanding of the production mechanisms in such collisions is of considerable interest. Measurements of the D* yield in jets probe the production processes in which the observed D* mesons are formed primarily from gluon splitting into c-cbar or b-bbar pairs. The charm content in jets is calculable in perturbative QCD, and the leading non-perturbative correction is expected to be significant at LHC energies. In this contribution we present latest results on performance studies of the reconstruction of charged D* mesons in jets in proton-proton collisions at √s = 10 TeV using the ALICE central detector. D*+ mesons are reconstructed through the decay sequence D*+ → D0 + π+ and D0 → K- + π+ (and its charge conjugate channel). The results are compared for different jet transverse momenta, and topological cut effects are discussed.
