- Abstract: The PHENIX experiment has measured open heavy-flavor production via semileptonic decay over the transverse momentum range 1 < pT < 6 GeV/c at forward and backward rapidity (1.4 < |y| < 2.0) in d+Au and p+p collisions at √sNN = 200 GeV. In central d+Au collisions an enhancement of heavy-flavor muon production is observed at backward rapidity, whereas suppression is seen at forward rapidity relative to the yield in p+p collisions scaled by the number of binary collisions. The difference observed between forward and backward rapidity exceeds predictions based on a model of initial parton density modification. These results can be used to probe predicted cold nuclear matter effects, which may significantly affect heavy-quark production at the Relativistic Heavy Ion Collider and the Large Hadron Collider, in addition to helping constrain the magnitude of charmonia breakup effects in nuclear matter.
