Measurement of heavy flavour
production in Pb-Pb

− A Large
Ion Collider Experiment (ALICE) at the Large Hadron Collider (LHC)
has been
built in order to identify and characterize the quark gluon plasma
(QGP)
created in high-energy nuclear collisions. As heavy flavour quarks
are produced at the
early stage of the collision, they serve as ideal probes for a
QGP. The ALICE
detector with its powerful
capabilities such as particle identification, secondary vertexing
at
sub-millimeter precision and tracking in a high multiplicity
environment
addresses the heavy flavour sector in nuclear collisions.We report latest on news
on the measurement
of open heavy flavour elliptic flow as well as on the measurement
of the
nuclear modification factor of open heavy flavour at unprecedented
high
energies of sNN = 2.76 TeV in Pb-Pb collisions. We will
also discuss
the status of the analysis of high-statistics data from the 2011
Pb-Pb run. Open
charmed hadrons are kinematically
reconstructed in the hadronic decay channels D0--> Kpi, D+
--> Kpipi,
andD*+
--> D0(Kpi)pi applying a
secondary decay-vertex topology. Complementary measurements are
performed by
detecting electrons (muons) from semileptonic decays of open heavy
flavoured
hadrons in the central (forward) region.
