Measurement of $C P$ violation in $B^{0} \to K_{S}^{0} I ¨ ^{0}$ decays at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +399

We report a measurement of the $C P$ -violating parameters $A$ and $S$ in $B^{0} \to K_{S}^{0} I ¨ ^{0}$ decays at Belle II using a sample of $387 \times 1 0^{6}$ $B B ˉ$ events reco…

Search for lepton-flavor-violating $I ¨ ^{-} \to ℓ^{-} K_{s}^{0}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +419

We present the results of a search for charged-lepton-flavor violating decays $I ¨ ^{-} \to ℓ^{-} K_{S}^{0}$ , where $ℓ^{-}$ is either an electron or a muon. We combine $…

Search for a long-lived spin-0 mediator in $b \to s$ transitions at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +411

Additional spin-0 particles appear in many extensions of the standard model. We search for long-lived spin-0 particles $S$ in $B$ -meson decays mediated by a $b \to s$ quark transiti…
