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 Darkonium in $e^+e^-$ Collisions / BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

The Belle II Physics Book / Belle-II Collaboration
We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB e+e- collider. Belle II collected its first collisions in 2018, and is expected to operate for the next decade. [...]

Modern experiments search for extremely rare processes hidden in much larger background levels. As the experiment complexity, the accelerator backgrounds and luminosity increase we need increasingly exclusive selections to efficiently select the rare events inside the huge background. [...]

This work presents the characterization of deep n-well (DNW) CMOS monolithic active pixel sensors (MAPS) fabricated in a 130 nm homogeneous, vertically integrated technology. An evaluation of the 3D MAPS device performance, designed for application of the experiments at the future high luminosity colliders, is provided through the characterization of the prototypes, including tests with infrared (IR) laser, 55Fe and 90Sr sources.
