| Popis: | In this talk, we report the evidence of B → hcK decay along with the first observation of the decay ηc(2S)→pp¯π+π− at Belle based on the full data sample accumulated by the Belle experiment at KEKB asymmetric energy e+e- collider. We also present search for B → Y (4260)K, B → X(3872)(→ χc1π0)K and B → X(3915)(→ χc1π0)K at Belle. As no signal is found, an upper limit on the product branching fractions is provided. |
