Abstract

We investigate modification of the bottom quark production due to cold nuclear matter effects (CNM) at mid-rapidity in d+Au collisions at √s_NN = 200 GeV at RHIC. Our results indicate that bottom production is not suppressed due to CNM effects in those collisions. We also found that shadowing and initial k_T breadboarding for charm quarks explains at low p_T (p_T < 3 GeV/c) the enhancement of heavy flavor decay electron yield in d+Au collisions at √s_NN = 200 GeV compared to p+p.
