Determination of $∣ V_{u b} ∣$ from untagged $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ decays using 2019-2021 Belle II data

Belle II Collaboration, K. Adamczyk, L. Aggarwal +588

We present an analysis of the charmless semileptonic decay $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ , where $ℓ = e, μ$ , from 198.0 million pairs of $B B ˉ$ mesons recorded by the Belle II…

Search for a light Higgs boson in single-photon decays of $Υ (1 S)$ using $Υ (2 S) \to π^{+} π^{-} Υ (1 S)$ tagging method

Belle Collaboration, S. Jia, C. P. Shen +210

We search for a light Higgs boson ( $A^{0}$ ) decaying into a $τ^{+} τ^{-}$ or $μ^{+} μ^{-}$ pair in the radiative decays of $Υ (1 S)$ . The production of $Υ (1 S)$ mesons is tagged by $Υ(2S)\to π^+…

Measurements of the branching fractions for $B \to K^{*} γ$ decays at Belle II

F. Abudinén, I. Adachi, R. Adak +565

This paper reports a study of $B \to K^{*} γ$ decays using $62.8 \pm 0.6$ fb $^{- 1}$ of data collected during 2019--2020 by the Belle II experiment at the SuperKEKB $e^{+} e^{-}$ asymm…

Study of $e^{+} e^{-} \to Υ (1S, 2S) η$ and $e^{+} e^{-} \to Υ (1S) η^{'}$ at $s = 10.866$ GeV with the Belle detector

Belle Collaboration, E. Kovalenko, A. Garmash +179

We report the first observation of the processes $e^{+} e^{-} \to Υ (1S, 2S) η$ at $s = 10.866$ ~GeV with a $10.2 σ$ and $16.5 σ$ significance respectively. The measured Born cross sec…
