Finding eta_c' and h_c at HERA-B

Abstract

The production of Charmonium states $\text{etacp}$ and $\text{hc}$ at fixed-target experiment of $pN$ collisions at HERA-$B$ is considered. It is found that the HERA-$B$ at DESY is one of the best machines in further confirming and detecting these two kinds of Charmonia in the near future.
