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. [...]

Validation of e$^+$e$^-$ Pair Production Total Cross Sections for Monte Carlo Particle Transport / Basaglia, Tulio (CERN) ; Begalli, Marcia (Rio de Janeiro State U.) ; Choi, Chansoo (Hanyang U.) ; Han, Min Cheol (Yonsei U.) ; Hoff, Gabriela (INFN, Genoa) ; Kim, Chan Hyeong (Hanyang U.) ; Pia, Maria Grazia (INFN, Genoa) ; Saracco, Paolo (INFN, Genoa)
Several sources of total cross sections for e$^+$e$^-$ pair production by photon interaction with matter, used by major Monte Carlo codes for particle transport, are quantitatively evaluated with respect to experimental measurements collected from the literature. They include data libraries deriving from theoretical calculations and analytical formulae representing empirical fits to tabulations. [...]

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.

First assessment of new Evaluated Data Libraries for Monte Carlo particle transport / Pia, Maria Grazia (INFN, Genoa) ; Basaglia, Tullio (CERN) ; Bonanomi, Matteo (Milan Bicocca U.) ; Cattorini, Federico (Milan Bicocca U.) ; Choi, Chansoo (Hanyang U.) ; Han, Min Cheol (INFN, Genoa) ; Hoff, Gabriela (Cagliari U. ; INFN, Cagliari) ; Kim, Chan Hyeong (Hanyang U.) ; Kim, Sung Hun (Hanyang U.) ; Marcoli, Matteo (Milan Bicocca U.) et al.
Evaluated data libraries are the foundation of physics modeling in Monte Carlo particle transport codes, such as Geant4, FLUKA and MCNP, which are used in high energy and nuclear physics experiments, accelerator studies and detector development. They encompass recommended cross sections, nuclear and atomic parameters, which may derive from theoretical calculations, evaluations of experimental data or a combination of both. [...]

Electron dosimetry in human skin: a reliability assessment of simulation scenarios / Basaglia, Tullio (CERN) ; Han, Haegin (Hanyang U.) ; Han, Min Cheol (INFN, Genoa) ; Kim, Chan Hyeong (Hanyang U.) ; Pia, Maria Grazia (INFN, Genoa)
The feasibility and reliability of Geant4-based simulation of human skin irradiation by low energy electrons (up to a few MeV) are reviewed, with emphasis on physics validation and the generation of a dedicated phantom for the simulation of Total Skin Electron Therapy..

Evaluated data libraries for electron-photon transport are most important components in Monte Carlo simulation and have been used in general-purpose Monte Carlo codes for decades. A new version of evaluated atomic data libraries, called EPICS2017, was released in early 2018. [...]
