Heavy-flavour multiplicity dependence in p-Pb collisions with ALICE at the LHC

The nuclear modification factor Q (pPb) of D(0), D(+) and D(*+) mesons is shown in the transverse-momentum (p (T)) range 1 < p (T) < 24 GeV/c as a function of centrality in p-Pb collisions at as measured with ALICE at the LHC. The Q (pPb) measured in different centrality intervals agree with each other for all D-meson species. Also presented are the self-normalized yields of D mesons in the same p (T) range and of electrons from semi-leptonic heavy-flavour hadron decays in the p (T) range 0.5 < p (T) < 8 GeV/c as a function of the charged-particle multiplicity. Both measurements agree with each other within their uncertainties. The self-normalized yields increase with the charged-particle multiplicity independent of the p (T) interval.
