The authors' main claim We find that decay width $\Xi_c(2923)^0\to\Xi_c^0\gamma$ and $\Xi_c(2923)^0\to\Xi_c^{'0}\gamma$ is evaluated to be approximately 1.23-11.66 KeV and 0.30-3.71 KeV, respectively.

In the present work, we study the radiative decay of newly observed $\Xi_c(2923)^0$ based on the successful explanation that $\Xi_c(2923)^0$ is an $S$-wave $D\Lambda-D\Sigma$ molecular state in our previous study~\cite{Zhu:2020jke}. The radiative decay width of $D\Lambda-D\Sigma$ molecular state into $\Xi_c^0\gamma$ final state through hadronic loops are evaluated using effective Lagrangians. We find that decay width $\Xi_c(2923)^0\to\Xi_c^0\gamma$ and $\Xi_c(2923)^0\to\Xi_c^{'0}\gamma$ is evaluated to be approximately 1.23-11.66 KeV and 0.30-3.71 KeV, respectively. These are different from the results~\cite{Wang:2020gkn,Bijker:2020tns} that obtained by assuming $\Xi_c(2923)^0$ may be conventional charmed baryon. If measurements are in future experimental, these differences will be very useful to help us to test various interpretations of $\Xi_c(2923)^0$.

In this work, we adopt the value $Λ=1.0$ GeV because it is determined from the experimental data of Refs. [ref] (and their references) within the same correlation function $Φ(y^2)$ adopted in current work.
