Abstract

We investigate the production of hyperons, charmed baryons, and potential hadronic molecular states in neutrino-proton $(\bar{\nu}_\mu p)$ reaction, a process characterized by a particularly clean final state. Employing effective Lagrangians, chiral perturbation theory, and a hadronic molecular model, we perform theoretical calculations for several relevant channels, including those leading to the formation of the hadronic molecular candidate $(\bar{D}N)$ and $(\bar{D}\Sigma)$. Our results indicate that future neutrino facilities could serve as a complementary platform for exploring exotic baryonic states and provide valuable insights into the dynamics of strong interactions in the strange and charm sectors.
