Abstract
We report a search for X(3872) and X(3915) in B+→χc1π0K+ decays. We set an upper limit of B(B+→X(3872)K+)×B(X(3872)→χc1π0)<8.1×10-6 and B(B+→X(3915)K+)×B(X(3915)→χc1π0)<3.8×10-5 at 90% confidence level. We also measure B(X(3872)→χc1π0)/B(X(3872)→J/ψπ+π-)<0.97 at 90% confidence level. The results reported here are obtained from 772×106 BB events collected at the (4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider.
