Ds+ production at central rapidity in Pb–Pb collisions at sNN=2.76 TeV with the ALICE detector

AbstractWe present measurements of the Ds+ 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 Ds+→ϕπ+→K+K−π+. Preliminary results of the Ds+ nuclear modification factor will be presented
