What can we learn from the electromagnetic properties of hidden-charm molecular pentaquarks with single strangeness?

Abstract

Inspired by the observation of the $P_{cs}(4459)$ and $P_{\psi s}^{\Lambda }(4338)$, we systematically investigate the magnetic moments, the transition magnetic moments, and the radiative decay behaviors of the $S$-wave isoscalar ${\Xi }_c^{(\prime )}{\bar{D}}^{(\ast )}$ molecular pentaquark states in this work. Our quantitative investigation shows that their electromagnetic properties can provide important hint to decode the inner structure of these discussed isoscalar ${\Xi }_c^{(\prime )}{\bar{D}}^{\ast }$ molecular pentaquarks. As the potential research issue, we suggest future experiment to focus on the electromagnetic properties of these isoscalar ${\Xi }_c^{(\prime )}{\bar{D}}^{(\ast )}$ molecular pentaquarks, which are a typical hidden-charm molecular pentaquark system with single strangeness.
