Measurement of the Ratio of Partial Branching Fractions of Inclusive $B \to X_{u} ℓ I^½$ to $B \to X_{c} ℓ I^½$ and the Ratio of their Spectra with Hadronic Tagging

Belle Collaboration, M. Hohmann, P. Urquijo +157

We present a measurement of the ratio of partial branching fractions of the semi-leptonic inclusive decays, $B \to X_{u} ℓ I^½$ to $\overline{B} \to X_{c} \el…

Search for Rare $b \to d ℓ^{+} ℓ^{-}$ Transitions at Belle

Belle, Belle II Collaborations, : +393

We present the results of a search for the $b \to d ℓ^{+} ℓ^{-}$ flavor-changing neutral-current rare decays $B^{+, 0} \to (I^\cdot, I ¨ , I ¨ ^{+, 0}, I ¨ ^{+, 0}) e^{+} e^{-}$ and $B^{+, 0} \to (…

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…
