B -meson production at forward and backward rapidity in p+p and Cu + Au collisions at sNN =200 GeV

Summary, in English

The fraction of J/ψ mesons which come from B-meson decay, FB→J/ψ, is measured for J/ψ rapidity 1.20 in p+p and Cu+Au collisions at sNN = 200 GeV with the PHENIX detector. The extracted fraction is FB→J/ψ=0.025±0.006 (stat) ± 0.010(syst) for p+p collisions. For Cu+Au collisions, FB→J/ψ is 0.094 ± 0.028(stat) ± 0.037(syst) in the Au-going direction (-2.2
