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

Abstract

In order to confirm the existence of the dibaryon state $d^{\ast }(2380)$ observed at WASA@COSY, we estimate the production of the possible dibaryon and anti-dibaryon pair $d^{\ast }{\bar{d}}^{\ast }$ at the energy region of the upcoming experiments at $\bar{\mathrm{P}}$anda. Based on some qualitative properties of $d^{\ast }$ 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.
