The radiative decay of $\psi(3770)$ into the predicted scalar state X(3700)

TL;DR

This paper predicts the radiative decay width of the $a(3770)$ into the scalar resonance X(3700), suggesting experimental observation could confirm X(3700)'s existence.

Contribution

It provides a theoretical calculation of the decay width for $a(3770)$ to X(3700), supporting future experimental detection.

Findings

Decay width calculation indicates observable signals at BEPC-II

Supports the existence of the scalar state X(3700)

Experimental confirmation feasible with upgraded facilities

Abstract

We calculate the radiative decay width of the $\psi(3770)$ into the dynamically generated scalar resonance X(3700) which is predicted in a previous paper. The results show that it is possible that the upgraded BEPC-II facility will generate enough statistics in order to observe this decay and thus confirm the existence of the X(3700).
