Abstract:	摘要： The PHENIX experiment has measured open heavy-flavor production via semileptonic decay over the transverse momentum range 1 < p(T) < 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, relative to the yield in p + p collisions scaled by the number of binary nucleon-nucleon collisions, a suppression is observed at forward rapidity (in the d-going direction) and an enhancement at backward rapidity (in the Au-going direction). Predictions using nuclear-modified-parton-distribution functions, even with additional nuclear-p(T) broadening, cannot simultaneously reproduce the data at both rapidity ranges, which implies that these models are incomplete and suggests the possible importance of final-state interactions in the asymmetric d + Au collision system. These results can be used to probe cold-nuclear-matter effects, which may significantly affect heavy-quark production, in addition to helping constrain the magnitude of charmonia-breakup effects in nuclear matter. 其他題名： Phys Rev Lett 出版者： United States 出版日期： 2014-06-27 出處： Physical review letters, 2014-06, Vol.112 (25), p.252301, Article 252301 資源來源： American Physical Society Journals 識別號： ISSN: 0031-9007 識別號： ISSN: 1079-7114 識別號： EISSN: 1079-7114 識別號： DOI: 10.1103/PhysRevLett.112.252301 識別號： PMID: 25014805
