Study of $e^{+}{e}^{-}\to {\pi }^{0}X(3872)\gamma$ and search for $Z_c(4020{)}^0\to X(3872)\gamma$

Abstract

Using data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies from 4.178 to 4.600 GeV, we study the process $e^{+}{e}^{-}\to {\pi }^{0}X(3872)\gamma$ and search for $Z_c(4020{)}^0\to X(3872)\gamma$. We find no significant signal and set upper limits on $\sigma (e^{+}{e}^{-}\to {\pi }^{0}X(3872)\gamma )\cdot \mathcal{B}(X(3872)\to {\pi }^{+}{\pi }^{-}J/\psi )$ and $\sigma (e^{+}{e}^{-}\to {\pi }^0{Z}_c(4020{)}^0)\cdot \mathcal{B}(Z_c(4020{)}^0\to X(3872)\gamma )\cdot \mathcal{B}(X(3872)\to {\pi }^{+}{\pi }^{-}J/\psi )$ for each energy point at $90\%$ confidence level, which is of the order of several tenths pb.
