Query: D meson production in Pb-Pb collisions with the ALICE detector   Open heavy-flavour hadrons are a powerful tool to investigate the properties
of the high-density medium created in heavy-ion collisions at high energies as
they come from the hadronization of heavy quarks. The latter are created in the
early stage of the interaction and experience the whole collision history.
Heavy quarks in-medium energy loss can be investigated by comparing the
heavy-flavour production cross sections in p-p and nucleus-nucleus collisions.
In addition, initial spatial anisotropy of the fireball is converted into
momentum anysotropy of final state particles, in particular the elliptic flow.
D mesons are identifed from their hadronic decays which can be reconstructed in
the central rapidity region using the tracking and PID detectors of the ALICE
detector.
