  We explore the quark mass effects on inclusive hadron production in
proton-nucleus collisions at high energies. We consider two processes. First,
we compute the single inclusive cross-section for production of hadrons with
open heavy flavour in the proton forward direction at leading order. Next, in
the same kinematics, we calculate the heavy-quark contribution to single
inclusive production of light or unidentified hadrons at next-to-leading-order.
For both studies we exploit the hybrid formalism, that is the collinear
factorisation on the proton side while high-density and high-energy effects are
resummed on the side of the nucleus.
