On the charge distribution of $d^*(2380)$

Abstract

We calculate the charge distributions of $d^*(2380)$. Two different interpretations of the $d^*$ are considered for a comparison. One is a compact explanation with coupled $ΔΔ+CC$ two-channel approximation in the chiral constituent quark model. Another is a resonance state of $D_{12}π$. The remarkable differences of the charge distributions in the two pictures are shown and it is expected that the future experiments may provide a clear test for the different theoretical interpretations.
