Photo-production of lowest ${\Sigma }_{1/2^{-}}^{\ast }$ state within the Regge-effective Lagrangian approach

Yun-He Lyu, Han Zhang, Neng-Chang Wei +3

Since the lowest ${\Sigma }^{\ast }$ state, with quantum numbers spin-parity $J^P=1/2^{-}$, is far from established experimentally and theoretically, we have performed a theoretical study o…
