Description
In high-energy proton-nucleus (pA) collisions, an incoming energetic parton crosses the target nucleus and suffers medium-induced, fully coherent gluon radiation. I will review the theoretical status of this effect, and present the phenomenological consequences of the corresponding fully coherent energy loss (FCEL) on light hadron, heavy meson and quarkonium production in pA collisions. I will briefly recall that the extrapolation of FCEL to AA collisions shows that this « cold nuclear matter effect » should not be neglected compared to the hot, QGP effects.
