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

Abstract
The study of open charm production in nucleus-nucleus collisions at the LHC is important because it allows to investigate in detail the mechanisms of heavy quarks production and energy loss in the hot and dense medium formed in the early stage of the collision and because open charm is the natural normalization for the J/psi production. The reconstruction of exclusive hadronic decays of charm particles is the only way to obtain a direct measurement of their pT distribution. We present the results of a feasibility study for the detection of D0 hadronic decays in Pb-Pb collisions with ALICE. The simulation assumes dNch/dy=8000 and a magnetic field of 0.2 Tesla. A complete description of the Inner Tracking System has been used in the simulation, while the responses of TPC and TOF were parameterized.
