Combined analysis of the decays ${\tau }^{-}\to K_S{\pi }^{-}{\nu }_{\tau }$ and ${\tau }^{-}\to K^{-}\eta {\nu }_{\tau }$

R. Escribano, S. González-Solís, M. Jamin +1

In a combined study of the decay spectra of ${\tau }^{-}\to K_S{\pi }^{-}{\nu }_{\tau }$ and ${\tau }^{-}\to K^{-}\eta {\nu }_{\tau }$ decays within a dispersive representation of the required form factors, we illustrate how the $K…
