Study of $\chi_{bJ}(nP) \rightarrow \omega \Upsilon(1S)$ at Belle / Belle Collaboration
We report results from a study of hadronic transitions of the $\chi_{bJ}(nP)$ states of bottomonium at Belle. [...]

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. [...]
