Search for a $τ^{+} τ^{-}$ resonance in $e^{+} e^{-} \to μ^{+} μ^{-} τ^{+} τ^{-}$ events with the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +464

We report the first search for a non-standard-model resonance decaying into $τ$ pairs in $e^{+} e^{-} \to μ^{+} μ^{-} τ^{+} τ^{-}$ events in the 3.6-10 GeV/ $c^{2}$ mass range. We u…

Search for a long-lived spin-0 mediator in $b \to s$ transitions at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +411

Additional spin-0 particles appear in many extensions of the standard model. We search for long-lived spin-0 particles $S$ in $B$ -meson decays mediated by a $b \to s$ quark transiti…

Precise measurement of the $D_{s}^{+}$ lifetime at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +359

We measure the lifetime of the $D_{s}^{+}$ meson using a data sample of 207 fb $^{- 1}$ collected by the Belle II experiment running at the SuperKEKB asymmetric-energy $e^{+} e^{-}$ collider…

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…

Novel method for the identification of the production flavor of neutral charmed mesons

Belle II Collaboration, I. Adachi, L. Aggarwal +396

We propose a new algorithm for the identification of the production flavor of neutral $D$ mesons in the Belle II experiment. The algorithm exploits the correlation between the flav…

Determination of $∣ V_{c b} ∣$ from $B \to D ℓ ν$ decays using 2019-2021 Belle II data

Belle II collaboration, F. Abudinén, I. Adachi +590

We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V_{c b}$ using $B \to D ℓ ν$ decays. The result is based on $e^{+} e^{-} \to Υ (4 S)$ data…
