Measurement of the inclusive semileptonic $B$ meson branching fraction in 62.8 fb$^{-1}$ of Belle II data / Belle-II Collaboration
We report a measurement of the branching fraction of inclusive semileptonic $B$ meson decays $B\to X_c\ell\nu\ell$ in $\Upsilon(4S)\to B\bar B$~data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider and corresponding to 62.8 fb$^{-1}$ of integrated luminosity.

Exclusive $B \to X_u \ell \nu_\ell$ Decays with Hadronic Full-event-interpretation Tagging in 62.8 fb$^{-1}$ of Belle II Data / Belle-II Collaboration
We present a reconstruction in early data of the semileptonic decay $B^+ \to \pi^0 \ell^+ \nu_\ell$, and first results of a reconstruction of the decays $B^+ \to \rho^0 \ell^+ \nu_\ell$ and $B^0 \to \rho^- \ell^+ \nu_\ell$ in a sample corresponding to 62.8 fb$^{-1}$ of Belle II data using hadronic $B$-tagging via the full-event-interpretation algorithm.

Measurements of branching fractions and CP-violating charge asymmetries in multibody charmless $B$ decays reconstructed in 2019-2020 Belle II data / Belle-II Collaboration
We report on measurements of branching fractions ($\mathcal{B}$) and CP-violating charge asymmetries ($\mathcal{A}_{\rm CP}$) of multibody charmless $B$ decays reconstructed by the Belle II experiment at the SuperKEKB electron-positron collider. [...]

Particle Identification in Belle II Silicon Vertex Detector / Hazra, S (Tata Inst.) ; Kaliyar, A B (Tata Inst.) ; Mohanty, G B (Tata Inst.) ; Adamczyk, K (Cracow, INP) ; Aihara, H (Tokyo U.) ; Aziz, T (Tata Inst.) ; Bacher, S (Cracow, INP) ; Bahinipati, S (Indian Inst. Tech., Bhubaneswar) ; Batignani, G (Pisa U. ; INFN, Pisa) ; Baudot, J (Strasbourg, IPHC) et al.
We report a particle identification (PID) tool developed using energy-loss information in the silicon-strip vertex detector (SVD) of Belle II for charged pions, kaons, and protons using \(D^{* + } \to D^{0}[ \to K^{ - }\pi ^{ + }]\pi ^{ + }\) and \(\Lambda \to p\pi ^{ - }\) decay samples. The study is based on e^+e^− collision data recorded at the \(\Upsilon (4S)\) resonance by Belle II and the results are compared with that of a Monte Carlo sample. [...]

Search for a light Higgs boson in single-photon decays of $\Upsilon(1S)$ using $\Upsilon(2S) \to \pi^+ \pi^- \Upsilon(1S)$ tagging method / Belle Collaboration
We search for a light Higgs boson ($A^0$) decaying into a $\tau^+\tau^-$ or $\mu^+\mu^-$ pair in the radiative decays of $\Upsilon(1S)$. The production of $\Upsilon(1S)$ mesons is tagged by $\Upsilon(2S)\to \pi^+ \pi^- \Upsilon(1S)$ transitions, using 158 million $\Upsilon(2S)$ events accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider.

Measurements of partial branching fractions of inclusive B→Xuℓ+νℓ decays with hadronic tagging / Belle Collaboration
We present measurements of partial branching fractions of inclusive semileptonic $B \to X_u \, \ell^+\, \nu_{\ell}$ decays using the full Belle data set of 711 fb$^{-1}$ of integrated luminosity at the $\Upsilon(4S)$ resonance and for $\ell = e, \mu$. Inclusive semileptonic $B \to X_u \, \ell^+\, \nu_{\ell}$ decays are CKM suppressed and measurements are complicated by the large background from CKM-favored $B \to X_c \, \ell^+\, \nu_{\ell}$ transitions, which have a similar signature.
