Observation of charmed strange meson pair production in $Υ (2 S)$ decays and in $e^{+} e^{-}$ annihilation at $s = 10.52 GeV$

Belle Collaboration, B. S. Gao, W. J. Zhu +165

We observe the process $Υ (2 S) \to D_{s}^{(*) +} D_{s J}^{-}$ and continuum production $e^{+} e^{-} \to D_{s}^{(*) +} D_{s J}^{-}$ at $s = 10.52$ GeV (and their charge conjugates) using the…

Tests of light-lepton universality in angular asymmetries of $B^{0} \to D^{*-} ℓ ν$ decays

Belle II Collaboration, I. Adachi, K. Adamczyk +416

We present the first comprehensive tests of light-lepton universality in the angular distributions of semileptonic $B^{0}$ -meson decays to charged spin-1 charmed mesons. We measure f…

Search for $C P$ violation using $T$ -odd correlations in $D_{(s)}^{+} \to K^{+} K^{-} π^{+} π^{0}$ , $D_{(s)}^{+} \to K^{+} π^{-} π^{+} π^{0}$ , and $D^{+} \to K^{-} π^{+} π^{+} π^{0}$ decays

Belle Collaboration, L. K. Li, A. J. Schwartz +174

We search for $C P$ violation using $T$ -odd correlations in five $D_{(s)}^{+}$ and $D_{(s)}^{-}$ four-body decays. Our analysis is based on 980 $f b^{- 1}$ of data collected by…

Search for lepton-flavor-violating $τ^{-} \to ℓ^{-} ϕ$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +575

We report a search for lepton-flavor-violating decays $τ^{-} \to ℓ^{-} ϕ$ ( $ℓ^{-} = e^{-}, μ^{-}$ ) at the Belle II experiment, using a sample of electron-positron data produced at the Su…
