Search for X(3872) and X(3915) decay into chi(c1)pi(0) in B decays at Belle
Original language description
We report a search for X(3872) and X(3915) in B+ ->chi(c1)pi K-0(+) decays. We set an upper limit of B(B+ -> X(3872)K+) x B(X(3872) -> chi(c1)pi(0)) < 8.1 x 10(-6) and B(B+ -> X(3915)K+) x B(X(3915) -> chi(c1)pi(0)) < 3.8 x 10(-5) at 90% confidence level. We also measure B(X(3872) -> chi(c1)pi(0))/B(X( 3872 ) -> (+)(-)(J/Psi pi)(pi)) < 0.97 at 90% confidence level. The results reported here are obtained from 772 x 10(6) B (B) over bar events collected at the Upsilon(45) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider.
