The Belle II Detector Upgrades Framework Conceptual Design Report

H. Aihara, A. Aloisio, D. P. Auguste +207

We describe the planned near-term and potential longer-term upgrades of the Belle II detector at the SuperKEKB electron-positron collider operating at the KEK laboratory in Tsukuba…

Silicon Vertex Detector of the Belle II Experiment

S. Mondal, K. Adamczyk, L. Aggarwal +72

The silicon vertex detector (SVD) is installed at the heart of the Belle II experiment, taking data at the high-luminosity $B$ -Factory SuperKEKB since 2019. The detector has shown…

Reconstruction of $B \to ρ ℓ ν_{ℓ}$ decays identified using hadronic decays of the recoil $B$ meson in 2019 -- 2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +580

We present results on the semileptonic decays $B^{0} \to ρ^{-} ℓ^{+} ν_{ℓ}$ and $B^{+} \to ρ^{0} ℓ^{+} ν_{ℓ}$ in a sample corresponding to 189.9/fb of Belle II data at the SuperKEKB $e…

Observation of Transverse $Λ/ Λ ˉ$ Hyperon Polarization in $e^{+} e^{-}$ Annihilation at Belle

The Belle Collaboration, A. Abdesselam, I. Adachi +445

We report the first observation of the polarization of $Λ/ Λ ˉ$ hyperons transverse to its production plane in $e^{+} e^{-}$ annihilation. We observe a significant polarization that ri…
