Production of the superheavy baryon Λ _{cbar{c}}^(ast)(4209) in kaon-induced reaction

The production of superheavy $\Lambda _{c\bar{c}}^{\ast }(4209)$ baryon in the $K^{-}p\rightarrow \eta _{c}\Lambda $ process via $s$-channel is investigated with an effective Lagrangian approach and the isobar model. Moreover, the $t$-channel with $K^{\ast }$ and $u$-channel with nucleon exchange are also considered, which are regarded as the background for the $\Lambda _{c\bar{c}}^{\ast }(4209)$ production in the $K^{-}p\rightarrow \eta_{c}\Lambda $ reaction. The numerical results indicate it is feasible to searching for the superheavy $\Lambda _{c\bar{c}}^{\ast }(4209)$ via $K^{-}p$ scattering. These theoretical results not only provide valuable informations to future experimental exploration of $\Lambda _{c\bar{c}}^{\ast }(4209)$ resonance but enable us to have a better understanding of the exotic baryons.
