Study of $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ (h = I ¨ , K, p)$ via initial-state radiation at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +417

Using a data sample of 427.9 fb $^{- 1}$ collected by the Belle~II detector at or near the $I^¥ (4 S)$ and $I^¥ (10753)$ resonances, the cross sections for $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ $ $(h=Ï/K…

First search for $B \to X_{s} I^½ I^ˉ ½$ decays

Belle II Collaboration, M. Abumusabh, I. Adachi +440

We report the first search for the flavor-changing neutral-current decays $B \to X_{s} I^½ I^ˉ ½$ , where $X_{s}$ is a hadronic system with strangeness equal to 1, in data co…

Search for the lepton-flavor-violating $I ¨ ^{-} \to e^{\mp} ℓ^{\pm} ℓ^{\mp}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +447

We present the result of a search for the charged-lepton-flavor violating decays $I ¨ ^{-} \to e^{\mp} ℓ^{\pm} ℓ^{-}$ , where $ℓ$ is a muon or an electron, using a data sampl…

Measurement of inclusive $B \to X_{u} ℓ I^½$ partial branching fractions and $∣ V_{u b} ∣$ at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +419

A sample of 365 fb $^{- 1}$ of $e^{+} e^{-} \to I^¥ (4 S) \to B B ˉ$ data collected by the Belle II experiment is used to measure the partial branching fractions of charmless semileptonic…

Test of lepton flavor universality with measurements of $R (D^{+})$ and $R (D^{*+})$ using semileptonic $B$ tagging at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +450

We report measurements of the ratios of branching fractions ${\cal R}(D^{(*)+}) = \frac{{\cal B}(\overline{B}{}^0 \to D^{(*)+} \,Ï^- \, \overlineÎ½_Ï)}{{\cal B}(\overline{B}{}^0…
