AB The measurement of prompt D-meson production as a function of multiplicityin p-Pb collisions atp√sNN = 5:02TeV with the ALICE detector at the LHC is reported.D0, D+ and D + mesons are reconstructed via their hadronic decay channels inthe centre-of-mass rapidity range -0:96 < ycms < 0:04 and transverse momentum interval1 < pT < 24 GeV=c. The multiplicity dependence of D-meson production is examined byeither comparing yields in p-Pb collisions in di erent event classes, selected based on themultiplicity of produced particles or zero-degree energy, with those in pp collisions, scaledby the number of binary nucleon-nucleon collisions (nuclear modi cation factor); as wellas by evaluating the per-event yields in p-Pb collisions in di erent multiplicity intervalsnormalised to the multiplicity-integrated ones (relative yields). The nuclear modi cationfactors for D0, D+ and D + are consistent with one another. The D-meson nuclear modi cation factors as a function of the zero-degree energy are consistent with unity withinuncertainties in the measured pT regions and event classes. The relative D-meson yields,calculated in various pT intervals, increase as a function of the charged-particle multiplicity.The results are compared with the equivalent pp measurements at√s = 7TeV as well aswith EPOS 3 calculations
