Invariant mass spectra of $τ^{-} \rightarrow h^{-}h^{-}h^{+}ν$
decays
   [PDF]

Ian M. Nugent
Using 342$fb^{-1}$ of $e^{+}e^{-}$ annihilation data collected with the BABAR detector at the SLAC PEP-II electron-positron asymmetric energy collider operating at a center-of-mass energies near 10.58GeV, we present the preliminary measurements of the invariant mass distributions of $\tau^{-} \rightarrow \pi^{-}\pi^{-}\pi^{+}\nu$, $\tau^{-} \rightarrow K^{-}\pi^{-}\pi^{+}\nu$, $\tau^{-} \rightarrow K^{-}\pi^{-}K^{+}\nu$ and $\tau^{-} \rightarrow K^{-}K^{-}K^{+}\nu$, where events with $K_{S}^{0}\rightarrow \pi^{-}\pi^{+}$ decays are excluded.
