Deeply bound dibaryon $d^{\ast }(2380)$ from meson-exchange saturation $\Delta \Delta$ effective field theory

Prin Sawasdipol, Chinadanai Bubpatate, Daris Samart

We propose an RG-improved effective-field-theory framework for the deeply bound dibaryon $d^{\ast }(2380)$, a $\Delta \Delta$ bound state in the $(J,I)=(3,0)$ ${}^7{S}_3$ channel. Its binding momentu…
