Study of the lowest tensor and scalar resonances in the $\tau \to \pi \pi \pi {\nu }_{\tau }$ decay

O. Shekhovtsova, J. J. Sanz-Cillero, T. Przedzinski

In this note we present a new parametrization of the hadronic current for the decay $\tau \to \pi \pi \pi {\nu }_{\tau }$ derived from the chiral lagrangian with explicit inclusion of resonances. We have…
