B-meson production at forward and backward rapidity in $p$+$p$ and Cu+Au collisions at $\sqrt{s_{{}_{NN}}}$=200 GeV

The fraction of $J/\psi$ mesons which come from B-meson decay, ${\text{F}}_{B\to J/\psi }$, is measured for J/$\psi$ rapidity \mbox{$1.2<|y|<2.2$} and $p_T>0$ in $p$+$p$ and Cu+Au c…
