Improved measurement of Born cross sections for $I ¨ _{b J} I ¨ $ and $I ¨ _{b J} (I ¨ ^{+} I ¨ ^{-} I ¨ ^{0})_{non - I ¨ }$ ( $J$ = 0, 1, 2) at Belle and Belle II

Belle, Belle II Collaborations, : +424

We study the processes $I ¨ _{b J} I ¨ $ and $I ¨ _{b J} (I ¨ ^{+} I ¨ ^{-} I ¨ ^{0})_{non - I ¨ }$ ( $J$ = 0, 1, 2) at center-of-mass energies $s$ from 10.73 to 11.02 GeV using a $142.5\,\mathr…

Measurement of $B \to K^{*} (892) I^^{3}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +451

We present measurements of $B \to K^{*} (892) I^^{3}$ decays using $365 fb^{- 1}$ of data collected from 2019 to 2022 by the Belle~II experiment at the SuperKEKB asymmetric-energ…

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…

Evidence for $B^{+} \to K^{+} I^½ I^ˉ ½$ decays

Belle II Collaboration, I. Adachi, K. Adamczyk +452

We search for the rare decay $B^{+} \to K^{+} I^½ I^ˉ ½$ in a $362 fb^{- 1}$ sample of electron-positron collisions at the $I^¥ (4 S)$ resonance collected with the Belle II…
