摘要
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^(*)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.
