Measurement of the $B^{0} \rightarrow D^{*-} \ell^{+} \nu_{\ell}$ branching ratio and $|V_{cb}|$ with a fully reconstructed accompanying $B$ meson in 2019-2021 Belle II data

F. Abudin'en, +580 more
TL;DR: In this paper , the authors presented a measurement of the branching ratio and CKM parameter of the Belle II data set of electron-positron collisions at the 4S resonance, corresponding to 189.3$\,$fb$^{-1}$ of integrated luminosity.

Measurement of the photon-energy spectrum in inclusive $B\rightarrow X_{s}\gamma$ decays identified using hadronic decays of the recoil $B$ meson in 2019-2021 Belle II data

B. I. C. F. Abudin'en, +591 more
TL;DR: In this article , the photon-energy spectrum in radiative bottom-meson (B ) decays into inclusive nuclear states involving a strange hadron and a photon. But the photon energy spectrum in B is not directly measured.

Study of Exclusive $B \to \pi e^+ \nu_e$ Decays with Hadronic Full-event-interpretation Tagging in 189.3 fb$^{-1}$ of Belle II Data

B. I. C. F. Abudin'en, +588 more
TL;DR: In this article , the authors presented a reconstruction of the semileptonic decays B 0 → π − e + ν e and B + → ε 0 e + ǫ 0 e − 1 in a sample corresponding to 189.3 fb − 1 of Belle II data, using events where the partner B -meson is reconstructed from a large variety of hadronic channels via a tagging algorithm known as the full-event interpretation.

Evidence for the singly Cabibbo-suppressed decay Ω c 0 → Ξ −

Determination of $|V_{cb}|$ from $B\to D\ell\nu$ decays using 2019-2021 Belle II data

B. I. C. F. Abudin'en, +588 more
TL;DR: In this article , the magnitude of the Cabibbo-KobayashiMaskawa (CKM) matrix element V cb using B → D(cid:96)ν decays was determined based on the Belle II detector corresponding to 189 . 2 fb − 1 of integrated luminosity.
