The PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) has measured meson production and its nuclear modification in asymmetric CuAu heavy-ion collisions at GeV at both forward Cu-going direction () and backward Au-going direction (), rapidities. The measurements are performed via the dimuon decay channel and reported as a function of the number of participating nucleons, rapidity, and transverse momentum. In the most central events, 0\%--20\% centrality, the meson yield integrated over GeV/ prefers a smaller value, which means a larger nuclear modification, in the Cu-going direction compared to the Au-going direction. Additionally, the nuclear-modification factor in CuAu collisions averaged over all centrality is measured to be similar to the previous PHENIX result in Au collisions for these rapidities.
