[BELLE2-CONF-PH-2020-010]
04 August 2020
The reconstruction of tau-pair production, $\epem \to \tau^{+}\tau^{-}$, from the subsequent 3-prong ($\tau^{+} \rightarrow \pi^{+} \pi^{-} \pi^{+} \bar{\nu}_{\tau}$) and 1-prong ($\tau^{-} \to \ell^{-} \bar{\nu}_{\ell} \nu_{\tau}$, $\tau^{-} \to h^{-} \nu_{\tau}$ or $\tau^{-} \to \pi^{-} \pi^0 \nu_{\tau}$) decays, is presented using 8.76~\invfb of $\epem $ collision data of {\belletwo} at the center-of-mass energy $\sqrt{s} = m_{\Upsilon(4S)}$ [...]
