Possible dibaryon production at $\bar{\rm{P}}$anda with a Lagrangian approach

Abstract

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