Measurements of D$^+_s$ production in pp, p—Pb and Pb—Pb collisions with ALICE at the LHC

ALICE has measured D+ production at mid-rapidity in pp (√8 =7 TeV), p-Pb (√8(NN) = 5.02 TeV) and Pb-Pb (√8(NN) =2.76 TeV) collisions, through the hadronic decay channel D(+)(s)⟶ϕΠ(+)⟶K(+) K(-)Π(+). The study of the D(+)(s)-meson production could reveal important details about charm-quark hadronisation in the Quark-Gluon Plasma (QGP). The measured D+ yields in pp and p-Pb collisions and the nuclear modification factors for central and semi-central Pb-Pb collisions will be shown here as a function of transverse momentum.
