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. [...]

Decays of the meson $B_{c}$ to a P-wave charmonium state $\chi_{c} or h_{C}$ / Chao Hsi Chang ; Yu Qi Chen ; Guo Li Wang ; Hong Shi Zong
The decays of the meson B/sub c/ to a P-wave charmonium state chi /sub c/ or h/sub c/ (here chi /sub c/ and h/sub c/ denote (cc[/sup 3 /P/sub J/]) and (cc[/sup 1/P/sub 1/]), respectively), the semileptonic ones B/sub c/ to chi /sub c/(h/sub c/)+l+ nu /sub l/, and the two-body nonleptonic ones B/sub c/ to chi /sub c/(h/sub c/)+h (h indicates a meson) are computed. To properly deal with the recoil effects, which may be relativistic in the decays, in the computation the framework of a heavy quark model, which is based on the Bethe- Salpeter equation and QCD inspired potential, is adopted. [...]

On Hadronic Production of the $B_c$ Meson ; rev. version / Chang, C H ; Chen, Y Q ; Han, G P ; Jiang, H T
Two of the approaches to the hadronic productions of the double heavy mesons $B_c$ and $B_c^*$ are investigated. Comparison in various aspects on the results obtained by the approaches is made and shown in figures and a table. [...]
