Abstract

We present the measurement of the D+s production in pp collisions at sqrt{s} = 7 TeV and in Pb Pb collisions at sqrt{s_NN} =2.76 TeV performed with the ALICE detector at central rapidity through the reconstruction of the hadronic decay channel D+s-> K+K-pi+. The preliminary results of the D+s nuclear modification factor will be presented.
