Provides theoretical support for experimental searches of dibaryon states.

Uses a covariant Lagrangian framework to model dibaryon production.

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 $d^*\bar{d}^*$ at the energy region of the upcoming experiments at $\bar{\rm{P}}$anda. 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.
