Production of the superheavy baryon ${\Lambda }_{c\bar{c}}^{\ast }(4209)$ in kaon-induced reaction

Abstract

The production of superheavy ${\Lambda }_{c\bar{c}}^{\ast }(4209)$ baryon in the $K^{-}p\to {\eta }_c\Lambda$ 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 $K^{-}p\to {\eta }_c\Lambda$ 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.
