Search for $B^0\to X(3872)\gamma$

Abstract

We report the results of a search for the decay $B^0\to X(3872)(\to J/\psi {\pi }^{+}{\pi }^{-})\gamma$. The analysis is performed on a data sample corresponding to an integrated luminosity of $711{\mathrm{fb}}^{-1}$ and containing $772\times 10^{6}B\bar{B}$ pairs, collected with the Belle detector at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider running at the ${\rm Y}(4S)$ resonance energy. We find no evidence for a signal and place an upper limit of $\mathcal{B}(B^0\to X(3872)\gamma )\times \mathcal{B}(X(3872)\to J/\psi {\pi }^{+}{\pi }^{-})<5.1\times 10^{-7}$ at 90% confidence level.
