Search for the X(1812) in $B^{\pm }\to K^{\pm }\omega \varphi$

Abstract

We report on a search for the X(1812) state in the decay $B^{\pm }\to K^{\pm }\omega \varphi$ with a data sample of $657\times 10^6$ $B\bar{B}$ pairs collected with the Belle detector at the KEKB $e^{+}{e}^{-}$ collider. No significant signal is observed. An upper limit $\mathcal{B}(B^{\pm }\to K^{\pm }X(1812),X(1812)\to \omega \varphi )<3.2\times 10^{-7}$ (90% C.L.) is determined. We also constrain the three-body decay branching fraction to be $\mathcal{B}(B^{\pm }\to K^{\pm }\omega \varphi )$ $<$ 1.9 $\times 10^{-6}$ (90% C.L.).
