Measurement of $C P$ asymmetries in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +436

We report measurements of time-dependent $C P$ asymmetries in $B^{0} \to K_{S}^{0} I ¨ ^{0} I^^{3}$ decays based on a data sample of $(388 \pm 6) \times 1 0^{6}$ $B B ˉ$ events collected at the $Î¥(4…

Measurement of $C P$ asymmetries in $B^{0} \to I^\cdot^{'} K_{s}^{0}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +399

We describe a measurement of charge-parity ( $C P$ ) violation asymmetries in $B^{0} \to I^\cdot^{'} K_{S}^{0}$ decays using Belle II data. We consider $I^\cdot^{'} \to I^\cdot (\to I^^{3} I^^{3}) I ¨ ^{+} I ¨ ^{-}$ and $Î·'\toÏ(\toÏ^…

Search for the decay $B^{0} \to I^^{3} I^^{3}$ using Belle and Belle II data

Belle, Belle II Collaborations, : +407

We report the result of a search for the rare decay $B^{0} \to I^^{3} I^^{3}$ using a combined dataset of $753 \times 1 0^{6}$ $B B ˉ$ pairs collected by the Belle experiment and $387\times…

Determination of the CKM angle $I ¨ _{3}$ from a combination of Belle and Belle II results

Belle, Belle II Collaborations, : +399

We report a determination of the CKM angle $I ¨ _{3}$ , also known as $I^^{3}$ , from a combination of measurements using samples of up to 711~fb $^{- 1}$ from the Belle experiment and up to…

New graph-neural-network flavor tagger for Belle II and measurement of $sin 2 I ¨ _{1}$ in $B^{0} \to J / I ¨ K_{S}^{0}$ decays

Belle II Collaboration, I. Adachi, L. Aggarwal +413

We present GFlaT, a new algorithm that uses a graph-neural-network to determine the flavor of neutral $B$ mesons produced in $I^¥ (4 S)$ decays. It improves previous algorithms by usi…

Search for a $I^¼^{+} I^¼^{-}$ resonance in four-muon final states at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +401

We report on a search for a resonance $X$ decaying to a pair of muons in $e^{+} e^{-} \to I^¼^{+} I^¼^{-} X$ events in the 0.212-9.000 GeV/ $c^{2}$ mass range, using 178 fb $^{- 1}$ o…
