Production of $etaprime$ Mesons in the $pp to ppetaprime$ Reaction at 3.67 GeV/c

The ratio of the total exclusive production cross sections for $etaprime$ and $eta$ mesons has been measured in the $pp$ reaction at $p_{beam}=3.67$ GeV/c. The observed $etaprime/eta$ ratio is $(0.83pm{0.11}^{+0.23}_{-0.18})times 10^{-2}$ from which the exclusive $etaprime$ meson production cross section is determined to be $(1.12pm{0.15}^{+0.42}_{-0.31})mu b$. Differential cross section distributions have been measured. Their shape is consistent with isotropic $etaprime$ meson production.
