D0, D+ and D + mesons are reconstructed via their hadronic decay channels in the centre-of-mass rapidity range -0:96 < ycms < 0:04 and transverse momentum interval 1 < pT < 24 GeV=c. The multiplicity dependence of D-meson production is examined by either comparing yields in p-Pb collisions in di erent event classes, selected based on the multiplicity of produced particles or zero-degree energy, with those in pp collisions, scaled by the number of binary nucleon-nucleon collisions (nuclear modi cation factor); as well as by evaluating the per-event yields in p-Pb collisions in di erent multiplicity intervals normalised to the multiplicity-integrated ones (relative yields). The nuclear modi cation factors 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 within uncertainties 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 as with EPOS 3 calculationseng© CERN, for the bene t of the ALICE Collaboration. Article funded by SCOAP3.
