Measurement of the presence of ${\mathrm{a}}_1(1420)$ and $\omega (782)$ in ${\tau }^{-}\to {\pi }^{-}{\pi }^{-}{\pi }^{+}{\nu }_{\tau }$ at Belle

Andrei Rabusov, Daniel Greenwald, Stephan Paul

We present preliminary results of a partial-wave analysis of ${\tau }^{-}\to {\pi }^{-}{\pi }^{-}{\pi }^{+}{\nu }_{\tau }$ using data from the Belle experiment at the KEKB ${\mathrm{e}}^{+}{\mathrm{e}}^{-}$ collider. We validate…
