Lepton-Flavor-Dependent Angular Analysis of $B \to K^{*} ℓ^{+} ℓ^{-}$

Belle Collaboration, S. Wehle, C. Niebuhr +200

We present a measurement of angular observables and a test of lepton flavor universality in the $B \to K^{*} ℓ^{+} ℓ^{-}$ decay, where $ℓ$ is either $e$ or $μ$ . The analysis is…

Measurement of $C P$ asymmetry in the $D^{0} \to K_{S}^{0} K_{S}^{0}$ decay at Belle

A. Abdesselam, I. Adachi, K. Adamczyk +447

We report a measurement of the time-integrated $C P$ asymmetry in the neutral charm meson decay $D^{0} \to K_{S}^{0} K_{S}^{0}$ using 921~fb $^{- 1}$ data collected at the $Υ (4 S)$ and $Υ (5 S)$ r…

Evidence for the decay $B^{0} \to η η$

A. Abdesselam, I. Adachi, K. Adamczyk +447

We report a search for $B^{0} \to η η$ with a data sample corresponding to an integrated luminosity of $698 fb^{- 1}$ containing $753 \times 1 0^{6}$ $B B ˉ$ pairs collected…
