This article mainly describes the estimation of the production cross section for the possible dibaryon and anti-dibaryon pair d*(d) over bar* in the upcoming experiments, in order to confirm the existence of the dibaryon state d*(2380) observed at WASA@COSY.
In order to confirm the existence of the dibaryon state d*(2380) observed at WASA@COSY, we estimate the cross section for production of the possible dibaryon and anti-dibaryon pair d*(d) over bar* in the energy region of the upcoming experiments at panda. Based on some qualitative properties of d* extracted from the analyses in the non-relativistic quark model, the production cross section for this spin-3 particle pair are calculated with the help of a phenomenological effective relativistic and covariant Lagrangian approach.
