We study the incoherent multiple scattering effects on heavy meson production in backward rapidity region of p+A collisions within generalized high-twist factorization formalism. calculate explicitly double contributions to differential cross sections by taking into account both initial-state and final-state interactions, find that these corrections are positive. further evaluate nuclear modification factor for muons come form semi-leptonic decays flavor mesons. Phenomenological applications d+Au at a center-of-mass energy s=200 GeV RHIC p+Pb s=5.02 TeV LHC presented. can describe rather well observed enhancement intermediate pT such reactions.
