Description
We study theoretically the feasibility of the semi-exclusive $^{12}$C($p,dp$)$X$ reaction for the observation of $\eta^\prime$ mesic nuclei using the transport model JAM. The semi-exclusive measurements of the ($p,d$) reaction with protons from $\eta^\prime$ absorption are found to be significant for the observation of the $\eta^\prime$ bound states.
Especially, the measurements of the energetic protons from $\eta^\prime$ non-mesic two-body absorption ($\eta^\prime NN \to NN$) are critically important.
We also study the $\eta^\prime p$ correlation function to determine the $\eta^\prime N$ interaction. We find that the $\eta^\prime p$ correlation function is a good observable to determine the sign of the $\eta^\prime p$ scattering length, which was not determined yet for the other experiments so far.
