- Abstract: We report e ±−µ ∓ pair yield from charm decay measured between midrapidity electrons (|η| < 0.35 and pT > 0.5 GeV/c) and forward rapidity muons (1.4 < η < 2.1 and pT > 1.0 GeV/c) as a function of ∆φ in both p+p and in d+Au collisions at √sNN = 200 GeV. Comparing the p+p results with several different models, we find the results are consistent with a total charm cross section σcc¯ = 538 ± 46 (stat) ± 197 (data syst) ± 174 (model syst) µb. These generators also indicate that the back-to-back peak at ∆φ = π is dominantly from the leading order contributions (gluon fusion), while higher order processes (flavor excitation and gluon splitting) contribute to the yield at all ∆φ. We observe a suppression in the pair yield per collision in d+Au. We find the pair yield suppression factor for 2.7 < ∆φ < 3.2 rad is JdA = 0.433 ± 0.087 (stat) ± 0.135 (syst), indicating cold nuclear matter modification of cc¯ pairs.
