Measurement of the branching fractions and mass spectra for $τ$
lepton decays including $K_{S}^{0}$ at Belle    [PDF]

S. Ryu

We report a study of $\tau$ lepton decays involving $\Ks$ with a 669 fb$^{-1}$ data sample accumulated with the Belle detector at the KEKB asymmetric-energy $e^{+}e^{-}$ collider. The branching fractions have been measured for the $\tauTO \piKs \nu_{\tau}$, $\KKs \nu_{\tau}$, $\piKspizero \nu_{\tau}$, $\KKspizero \nu_{\tau}$, $\piKsKs \nu_{\tau}$ and $\piKsKspizero \nu_{\tau}$ decays. We also provide the unfolded mass spectra for $\tauTO \piKspizero \nu_{\tau}$ and $\tauTO \KKspizero \nu_{\tau}$.
