Study of open-charm decays and radiative transitions of the X(3872)

Abstract

The processes $X(3872)\to D^{\ast 0}\overline{D^0}+c.c.,\gamma J/\psi ,\gamma \psi (2S),$ and $\gamma D^{+}{D}^{-}$ are searched for in a $9.0\mathrm{f}{\mathrm{b}}^{-1}$ data sample collected at center-of-mass energies between $4.178$ and $4.278$ GeV with the BESIII detector. We observe $X(3872)\to D^{\ast 0}\overline{D^0}+c.c.$ and find evidence for $X(3872)\to \gamma J/\psi$ with statistical significances of $7.4\sigma$ and $3.5\sigma$, respectively. No evident signals for $X(3872)\to \gamma \psi (2S)$ and $\gamma D^{+}{D}^{-}$ are found, and upper limit on the relative branching ratio $R_{\gamma \psi }\equiv \frac{\mathcal{B}(X(3872)\to \gamma \psi (2S))}{\mathcal{B}(X(3872)\to \gamma J/\psi )}<0.59$ is set at 90$\%$ confidence level. Measurements of branching ratios relative to decay $X(3872)\to {\pi }^{+}{\pi }^{-}J/\psi$ are also reported for decays $X(3872)\to D^{\ast 0}\overline{D^0}+c.c.,\gamma \psi (2S),\gamma J/\psi$, $\gamma D^{+}{D}^{-}$, as well as the non-$D^{\ast 0}{\bar{D}}^0$ three-body decays ${\pi }^0{D}^0{\bar{D}}^0$ and $\gamma D^0{\bar{D}}^0$.
