(Wayne State U.) et al.
This work shows how it is possible to reconstruct SuperKEKB's beam parameters using a Neural Network with beamstrahlung signal from the Large Angle Beamstrahlung Monitor (LABM) as input. We describe the device, the model, and discuss the results..

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. [...]

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. [...]

Measurement of Michel Parameters ($\bar\eta$, $\xi\kappa$) in the radiative leptonic decay of tau at Belle / Belle Collaboration
We present the first measurement of the Michel parameters $\bar{\eta}$ and $\xi\kappa$ in the radiative leptonic decay of the $\tau$ lepton using 703 f$\mathrm{b}^{-1}$ of data collected with the Belle detector at the KEKB $e^+e^-$ collider. The Michel parameters are measured by an unbinned maximum likelihood fit to the kinematic information of $e^+e^-\rightarrow\tau^+\tau^-\rightarrow (\pi^+\pi^0 \bar{\nu})(l^-\nu\bar{\nu}\gamma)$ $(l=e$ or $\mu)$.

Angular analysis of $B^0 \to K^\ast(892)^0 \ell^+ \ell^-$ / Belle Collaboration
We present a measurement of angular observables, $P_4'$, $P_5'$, $P_6'$, $P_8'$, in the decay $B^0 \to K^\ast(892)^0 \ell^+ \ell^-$, where $\ell^+\ell^-$ is either $e^+e^-$ or $\mu^+\mu^-$. [...]

Measurement of the branching ratio of $\bar{B}^0 \rightarrow D^{*+} \tau^- \bar{\nu}_{\tau}$ relative to $\bar{B}^0 \rightarrow D^{*+} \ell^- \bar{\nu}_{\ell}$ decays with a semileptonic tagging method / Belle Collaboration
We report a measurement of ratio ${\cal R}(D^*) = {\cal B}(\bar{B}^0 \rightarrow D^{*+} \tau^- \bar{\nu}_{\tau})/{\cal B}(\bar{B}^0 \rightarrow D^{*+} \ell^- \bar{\nu}_{\ell})$, where $\ell$ denotes an electron or a muon. The results are based on a data sample containing $772\times10^6$ $B\bar{B}$ pairs recorded at the $\Upsilon(4S)$ resonance with the Belle detector at the KEKB $e^+ e^-$ collider. [...]

Energy scan of the $e^+e^- \to h_b(nP)\pi^+\pi^-$ $(n=1,2)$ cross sections and evidence for the $\Upsilon(11020)$ decays into charged bottomonium-like states / Belle Collaboration
Using data collected with the Belle detector in the energy region of the $\Upsilon(10860)$ and $\Upsilon(11020)$ resonances we measure the $e^+e^- \to h_b(nP)\pi^+\pi^-$ $(n=1,2)$ cross sections. Their energy dependences show clear $\Upsilon(10860)$ and $\Upsilon(11020)$ peaks with a small or no non-resonant contribution. [...]

Resonance structure of $\tau^{-} \to K^{-}\pi^{+}\pi^{-}\nu_{\tau}$ decays / CLEO Collaboration
Using a sample of 4.7 fb/sup -1/ integrated luminosity accumulated with the CLEO II detector at the Cornell Electron Storage Ring (CESR) , we investigate the mass spectrum and resonant structure in tau /sup -/ to K/sup -/ pi /sup +/ pi /sup -/ nu /sub tau / decays. We measure the relative fractions of K/sub 1/(1270) and K/sub 1/(1400) resonances in these decays, as well as the K/sub 1/ masses and widths. [...]
