The analysis is performed on a data sample corresponding to an integrated luminosity of 711 fb-1 containing 772×106 BB pairs, collected at the (4S) resonance with the Belle detector at the asymmetric-energy e+e- collider KEKB. The result is consistent with standard model (SM) expectations, where the largest discrepancy from a SM prediction is observed in the muon modes with a local significance of 2.6σ. ? 2017 American Physical Society. |
