Evidence for and observation of
Abstract
A search for the decays and is performed. Evidence for the decay is found; its significance is . No evidence is found for . The branching fraction for is measured to be ; the upper limit for the branching fraction is at 90% C.L. In addition, a study of the invariant mass distribution in the channel results in the first observation of the decay with significance. The analysis is based on the data sample collected by the Belle detector at the asymmetric-energy collider KEKB at the resonance.

abstractNote = {A search for the decays B+→hcK+ and B0→hcKS0 is performed. Evidence for the decay B+→hcK+ is found; its significance is 4.8σ. No evidence is found for B0→hcKS0. The branching fraction for B+→hcK+ is measured to be (3.7-0.9+1.0 -0.8+0.8)×10-5; the upper limit for the B0→hcKS0 branching fraction is 1.4×10-5 at 90% C.L. In addition, a study of the pp¯π+π- invariant mass distribution in the channel B+→(pp¯π+π-)K+ results in the first observation of the decay ηc(2S)→pp¯π+π- with 12.1σ significance. The analysis is based on the 711 fb-1 data sample collected by the Belle detector at the asymmetric-energy e+e- collider KEKB at the γ(4S) resonance.},
