Feasibility study for the detection of D0 hadronic decays in Pb-Pb collisions at LHC with ALICE

Abstract
The ALICE experiment at the CERN LHC collider is devoted to the study of heavy-ion collisions at a centre of mass energy of 5.5 TeV per nucleon. The study of open charm production in nucleus-nucleus collisions at the LHC allows to investigate the mechanisms of heavy quark production and energy-loss in the hot and dense medium formed in the early stage of the collision. In addition, the open charm production cross-section is the natural normalization for the study of J/psi production. The reconstruction of exclusive hadronic decays of charm particles is the only way to obtain a direct measurement of their transverse momentum distribution. We present the results of a feasibility study for the detection of $D^0\to K^-\pi^+$ decays in Pb-Pb collisions with ALICE.
