Abstract

We present the measurement of the D+ s production in pp collisions at √ s = 7 TeV and in Pb– Pb collisions at √ sNN =2.76 TeV performed with the ALICE detector at central rapidity through the reconstruction of the hadronic decay channel D+ s → φπ+ → K +K −π + . The preliminary results of the D+ s nuclear modification factor will be presented.
