Search for B -> phi pi decays

Abstract

We report on a search for the charmless decays $B^{+}\to \varphi {\pi }^{+}$ and $B^0\to \varphi {\pi }^0$ that are strongly suppressed in the Standard Model. The analysis is based on a data sample of $657\times 10^6$ $B\bar{B}$ pairs collected at the ${\rm Y}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy $e^{+}{e}^{-}$ collider. We find no significant signal and set upper limits of $3.3\times 10^{-7}$ for $B^{+}\to \varphi {\pi }^{+}$ and $1.5\times 10^{-7}$ for $B^0\to \varphi {\pi }^0$ at the 90% confidence level.
