Nuclear effects on open charm production in p+A reactions
Ivan Vitev, T. Goldman, Mikkel Johnson, Jian-Wei Qiu
Abstract
We calculate and resum the nuclear enhanced power corrections from the final state partonic scattering in nuclear matter to open charm production and correlations. In p+A reactions, we find that single and double inclusive D mesons can be suppressed as much as the neutral pions from the dynamical high twist shadowing. Effects of initial state energy loss in p+A collisions are also investigated and may lead to significantly weaker transverse momentum dependence of the nuclear suppression.
