Abstract

In order to confirm the existence of the dibaryon state observed at WASA@COSY, we estimate the cross section for production of the possible dibaryon and anti-dibaryon pair in the energy region of the upcoming experiments at anda. Based on some qualitative properties of 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.
