Role of the hidden charm $N_{c\bar{c}}^{\ast }(4261)$ resonance in the ${\pi }^{-}p\to J/\psi n$ reaction

Zhen Ouyang, Li-Ping Zou

We employ an effective Lagrangian approach and isobar model to investigate the role of the $N_{c\bar{c}}^{\ast }(4261)$ resonance with hidden charm in the ${\pi }^{-}p\to J/\psi n$ reaction. The…
