Query: Detection of D^0 mesons via hadronic decays in Pb-Pb collisions at LHC
  with ALICE   The ALICE experiment is devoted to the study of heavy-ion collisions at the
CERN LHC collider. We present the results of a feasibility study for the
detection of D^0 \to K^-\pi^+ decays in Pb-Pb collisions with ALICE.
