Search for the $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decay

Belle, Belle II Collaborations, : +432

We present the first search for $B^{0} \to K_{S}^{0} I ¨ ^{+} I ¨ ^{-}$ decays. We look for signal decays in $B^{0} B ˉ^{0}$ events produced in asymmetric-energy electron-positron collisions.…

Searches for charged-lepton-flavor violation in $χ_{b J} (1 P)$ decays

Belle, Belle II Collaborations, : +425

We report the first searches for charged-lepton-flavor violation in decays of $χ_{b J} (1 P)$ ( $J = 0, 1,$ and $2$ ) to a pair of charged leptons using 158 million $Υ (2 S)$ decays collect…

Measurement of mixing-induced CP violation in the decay $B^{0} \to I ¨ ^{0} I ¨ ^{0}$

Belle II Collaboration, M. Abumusabh, I. Adachi +437

Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…

Observation of the radiative decay $D_{s} (2317)^{+} \to D_{s}^{*} I^^{3}$

Belle II Collaboration, M. Abumusabh, I. Adachi +367

We observe the radiative decay $D_{s 0}^{*} (2317)^{+} \to D_{s}^{*+} I^^{3}$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the conti…

Measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +416

We perform a measurement of time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays using a dataset of approximately $772 \times 1 0^{6}$ and $521 \times 10…
