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. [...]

Two new bands have been identified in $^{137}$Nd from a high-statistics JUROGAM II gamma-ray spectroscopy experiment. Constrained density functional theory and particle rotor model calculations are used to assign configurations and investigate the band properties, which are well described and understood. [...]

Transverse broadband impedance reduction techniques in a heavy ion accelerator / Chen, X Q (Lanzhou, Inst. Modern Phys. ; Beijing, GUCAS ; Unlisted, CN) ; Zhu, G Y (Lanzhou, Inst.

Modern Phys. ; Unlisted, CN) ; Ruan, S (Lanzhou, Inst. Modern Phys. ; Unlisted, CN) et al.
The transverse broadband impedances of major components in the BRing (booster ring) of HIAF (High Intensity Heavy-ion Accelerator Facility) are estimated using the analytical formulas or the wakefield solver in the CST Studio Suite. At low frequency, the transverse broadband impedance model of BRing is Z1H(ω)=-417.14i  kΩ/m(horizontal) and Z1V(ω)=-530.19i kΩ/m(vertical), which are larger than the threshold impedance for the transverse mode-coupling instability.

Mixing effects on K-forbidden transition rates from the 6+ isomers in the N = 104 isotones / Chen, Fang-Qi (Shanghai Jiaotong U.) ; Dracoulis, G.D (Australian Natl. U., Canberra) ; Sheikh, J.A (Kashmir U ; Tennessee U.) ; Shimizu, Y.R (Kyushu U.) ; Sun, Yang (Tennessee U ; Lanzhou, Inst. Modern Phys ; Shanghai Jiaotong U.) ; Walker, P.M (CERN ; Surrey U.)
The problem of the very different E2 decay rates from the two-quasineutron K(I ) = 6(+) isomers in the N = 104 isotones (172)Er, (174)Yb, (176)Hf, and (178)W is investigated using the triaxial projected shell model with inclusion of multi-quasiparticle configurations. It is demonstrated that the highly K-forbidden transition from the 6(+) isomer to the ground-state band is sensitive to mixing with the 6(+) state of the l-vibrational band. [...]
