Abstract

We present a measurement of angular observables and a test of lepton flavor universality in the B→K∗ℓ+ℓ- decay, where ℓ is either e or μ. 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.
