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* ■* in the energy region of the upcoming experiments at ■anda. Based on some qualitative properties of d* extracted from the analyses in the nonrelativistic 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.
