Measurement of Prompt D-Meson Production in p-Pb Collisions at sNN=5.02 TeV

The pT-differential production cross sections of the prompt charmed mesons DO, D+, D*+, and Ds+ and their charge conjugate in the rapidity interval -0.96 0.04 were measured in p-Pb collisions at a center-of-mass energy sNN=5.02 TeV with the ALICE detector at the LHC. The nuclear modification factor RpPb, quantifying the D-meson yield in p-Pb collisions relative to the yield in pp collisions scaled by the number of binary nucleon-nucleon collisions, is compatible within the 15%-20% uncertainties with unity in the transverse momentum interval 1
