Successful reconstruction of D0 and D+ mesons in simulated data

Feasibility established for studying D-mesons in hadronic channels at LHC energies

Potential for future heavy-ion collision studies with these methods

Abstract

At LHC energy, heavy quarks will be abundantly produced and the design of the ALICE Experiment will allow us to study their production using several channels. We investigate the feasibility of the study of D mesons reconstructed in their exclusive hadronic decay channel. After reviewing the ALICE potential for such studies, we will present some results for the two more promising decay channels i.e D0->KPi and D+ -> K-Pi+Pi+ obtained with 7 TeV pp data and 5.5 A TeV Pb-Pb Monte Carlo data .
