Title: Search for X ( 3872 ) and X ( 3915 ) decay into χ c 1 π 0 in B decays at Belle

Abstract

We report a search for X ( 3872 ) and X(3915) in B + χ c 1 π 0 K + decays. We set an upper limit of B ( B + X ( 3872 ) K + ) × B ( X ( 3872 ) χ c 1 π 0 ) < 8.1 × 10 - 6 and B ( B + X ( 3915 ) K + ) × B ( X ( 3915 ) χ c 1 π 0 ) < 3.8 × 10 - 5 at 90% confidence level. We also measure B ( X ( 3872 ) χ c 1 π 0 ) / B ( X ( 3872 ) J / ψ π + π - ) < 0.97 at 90% confidence level. The results reported here are obtained from 772 × 10 6 B B ¯ events collected at the Υ ( 4 S ) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.
