Reconstruction of $B \to I ¨ ℓ I^½_{ℓ}$ decays identified using hadronic decays of the recoil $B$ meson in 2019 -- 2021 Belle II data

Belle II Collaboration, F. AbudinÃ©n, I. Adachi +580

We present results on the semileptonic decays $B^{0} \to I ¨ ^{-} ℓ^{+} I^½_{ℓ}$ and $B^{+} \to I ¨ ^{0} ℓ^{+} I^½_{ℓ}$ in a sample corresponding to 189.9/fb of Belle II data at the SuperKEK…

First Measurements of Beam Backgrounds at SuperKEKB

P. M. Lewis, I. Jaegle, H. Nakayama +67

The high design luminosity of the SuperKEKB electron-positron collider is expected to result in challenging levels of beam-induced backgrounds in the interaction region. Properly s…
