Measurement of $C P$ asymmetries in $B^{0} \to K_{S}^{0} π^{0} γ$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +436

We report measurements of time-dependent $C P$ asymmetries in $B^{0} \to K_{S}^{0} π^{0} γ$ decays based on a data sample of $(388 \pm 6) \times 1 0^{6}$ $B B ˉ$ events collected at the $Υ (4 S)$ …

Measurement of the $e^{+} e^{-} \to π^{+} π^{-} π^{0}$ cross section in the energy range 0.62-3.50 GeV at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +360

We report a measurement of the $e^{+} e^{-} \to π^{+} π^{-} π^{0}$ cross section in the energy range from 0.62 to 3.50 GeV using an initial-state radiation technique. We use an $e^{+} e^{-}$ data sa…

Measurement of $C P$ asymmetries in $B^{0} \to η^{'} K_{s}^{0}$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +399

We describe a measurement of charge-parity ( $C P$ ) violation asymmetries in $B^{0} \to η^{'} K_{S}^{0}$ decays using Belle II data. We consider $η^{'} \to η (\to γ γ) π^{+} π^{-}$ and $η^{'} \to ρ (\to π^{+} π^{-}) γ$ de…

First Measurement of $R (X_{τ / ℓ})$ as an Inclusive Test of the $b \to c τ ν$ Anomaly

Belle II Collaboration, I. Adachi, K. Adamczyk +390

We measure the tau-to-light-lepton ratio of inclusive $B$ -meson branching fractions $R (X_{τ / ℓ}) \equiv B (B \to X τ ν) / B (B \to X ℓ ν)$ , where $ℓ$ indicate…

Determination of $∣ V_{c b} ∣$ using $B^{0} \to D^{*+} ℓ^{-} ν ˉ_{ℓ}$ decays with Belle II

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

We determine the CKM matrix-element magnitude $∣ V_{c b} ∣$ using $B^{0} \to D^{*+} ℓ^{-} ν ˉ_{ℓ}$ decays reconstructed in $189 fb^{- 1}$ of collision data collec…

Search for Lepton-Flavor-Violating $τ$ Decays to a Lepton and an Invisible Boson at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +398

We search for lepton-flavor-violating $τ^{-} \to e^{-} α$ and $τ^{-} \to μ^{-} α$ decays, where $α$ is an invisible spin-0 boson. The search uses electron-positron collisions at $10.58$ GeV cen…
