Abstract content <br> (Max 300 words)
Heavy quarks and quarkonium states are believed to be sensitive probes for the study of the
evolution as well as the properties of the hot and dense medium, formed in ultra-relativistic heavyion
collisions, since they are produced at a very early stage in the initial hard scattering processes.
Apart from providing the crucial reference for nucleus-nucleus collisions, proton-proton collisions
are also of great interest as they allow a test of perturbative QCD in a new regime of low Bjorken-x
values at the LHC.
The ALICE detector has proven to have excellent tracking, particle identification as well as precise
vertexing capabilities. These specific detector characteristics result in a low momentum reach for
quarkonia and open heavy-flavour hadrons which is unique to the LHC. One approach to e.g. J/ψ and
heavy-flavour measurements is via their decay leptons which are measured at mid-rapidity in the
central barrel and the muon spectrometer at forward rapidity.
In this talk, after giving a brief description of the detector, we will present the latest results from
measurements of J/ψ from di-leptonic decays and of leptons from heavy-flavour hadron decays at
both forward (2.5 < η < 4.0) and central (|η| < 0.9) rapidity in pp collisions at √s = 2.76 and 7 TeV and
their nuclear modification factor (RAA) in Pb-Pb collisions at √sNN = 2.76 TeV.
