We calculate and resum the nuclear enhanced power corrections from the finalstate partonic scattering in nuclear matter to open charm production andcorrelations. In p+A reactions, we find that single and double inclusive Dmesons can be suppressed as much as the neutral pions from the dynamical hightwist shadowing. Effects of initial state energy loss in p+A collisions arealso investigated and may lead to significantly weaker transverse momentumdependence of the nuclear suppression.Comment: Poster proceedings for Quark Matter 2005.
