Observation of the radiative decay $D_{s} (2317)^{+} \to D_{s}^{*} γ$

Belle II Collaboration, M. Abumusabh, I. Adachi +367

We observe the radiative decay $D_{s 0}^{*} (2317)^{+} \to D_{s}^{*+} γ$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the contin…

Measurement of $B \to K^{*} (892) γ$ decays at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +451

We present measurements of $B \to K^{*} (892) γ$ decays using $365 fb^{- 1}$ of data collected from 2019 to 2022 by the Belle~II experiment at the SuperKEKB asymmetric-energy…

Determination of the CKM angle $ϕ_{3}$ from a combination of Belle and Belle II results

Belle, Belle II Collaborations, : +399

We report a determination of the CKM angle $ϕ_{3}$ , also known as $γ$ , from a combination of measurements using samples of up to 711~fb $^{- 1}$ from the Belle experiment and up to 3…

Search for a dark leptophilic scalar produced in association with $τ^{+} τ^{-}$ pair in $e^{+} e^{-}$ annihilation at center-of-mass energies near 10.58 GeV

Belle Collaboration, D. Biswas, Sw. Banerjee +177

A dark leptophilic scalar $(ϕ_{L})$ is a hypothetical particle that couples only to leptons rather than quarks. We report on a search for $ϕ_{L}$ in the $e^+e^- \to τ^+ τ^- ϕ_L, ~ϕ_L \…
