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 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…

Observation of $B \to D^{(*)} K^{-} K_{S}^{0}$ decays using the 2019-2022 Belle II data sample

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

We present a measurement of the branching fractions of four $B^{0, -} \to D^{(*) +, 0} K^{-} K_{S}^{0}$ decay modes. The measurement is based on data from SuperKEKB electron-positron colli…

First Experimental Study of the Purely Leptonic Decay $D_{s}^{*+} \to e^{+} ν_{e}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using $7.33 fb^{- 1}$ of $e^{+} e^{-}$ collision data taken with the BESIII detector at the BEPCII collider, we report the first experimental study of the purely leptonic decay…

Measurement of the $B^{0} \to D^{*-} ℓ^{+} ν_{ℓ}$ branching ratio and $∣ V_{c b} ∣$ with a fully reconstructed accompanying $B$ meson in 2019-2021 Belle II data

F. Abudinén, I. Adachi, K. Adamczyk +581

We present a measurement of the $B^{0} \to D^{*-} ℓ^{+} ν_{ℓ}$ ( $ℓ = e, μ$ ) branching ratio and of the CKM parameter $∣ V_{c b} ∣$ using signal decays accompanied by a f…
