Role of $Y(4630)$ in the $p\bar{p}\rightarrow\Lambda_c\bar{\Lambda}_c$ reaction near threshold
We investigate the charmed baryon production reaction $p\bar{p}\rightarrow\Lambda_c\bar{\Lambda}_c$ in an effective Lagrangian approach. Besides the $t$-channel $D^0$ and $D^{*0}$ mesons exchanges, the $s$-channel $Y(4630)$ meson exchange is taken into account. For the total cross sections, the $D^0$ and $D^{*0}$ mesons provide minor background contributions, while the $Y(4630)$ state gives a clear peak structure with the magnitude of 10 $\mu$b at center of mass energy 4.63 GeV. Basing on the results, we suggest that the reaction of $p\bar{p}\rightarrow\Lambda_c\bar{\Lambda}_c$ can be used to search for the $1^{--}$ charmonium-like $Y(4630)$ state, and our predictions can be tested in future by the $\rm{\bar PANDA}$ facility.
