We report measurements of branching fractions and time-dependent $CP$ asymmetries in ${B}^{0}\ensuremath{\rightarrow}{D}^{+}{D}^{\ensuremath{-}}$ and ${B}^{0}\ensuremath{\rightarrow}{D}^{*\ifmmode\pm\else\textpm\fi{}}{D}^{\ensuremath{\mp}}$ decays using a data sample that contains $(772\ifmmode\pm\else\textpm\fi{}11)\ifmmode\times\else\texttimes\fi{}{10}^{6}B\overline{B}$ pairs collected at the $\ensuremath{\Upsilon}(4S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. We determine the branching …

The mass of the $\ensuremath{\tau}$ lepton has been measured in the decay mode $\ensuremath{\tau}\ensuremath{\rightarrow}3\ensuremath{\pi}{\ensuremath{\nu}}_{\ensuremath{\tau}}$ using a pseudomass technique. The result obtained from $414\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of data collected with the Belle detector is ${M}_{\ensuremath{\tau}}=[1776.61\ifmmode\pm\else\textpm\fi{}0.13(\mathrm{stat})\ifmmode\pm\else\textpm\fi{}0.35(\mathrm{sys})]\text{ }\text{ }\mathrm{MeV}/{c}^{2}$. The upper limit on the relative …

The inclusive production of ${D}_{s}$, ${D}^{0}$, and $J/\ensuremath{\psi}$ mesons is studied using a $1.86\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ data sample collected on the $\ensuremath{\Upsilon}(5S)$ resonance with the Belle detector at the KEKB asymmetric-energy ${e}^{+}{e}^{\ensuremath{-}}$ collider. The number of $b\overline{b}$ events in this $\ensuremath{\Upsilon}(5S)$ data …
