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