${\tau }^{-}\to K^{-}{\eta }^{(\prime )}{\nu }_{\tau }$ decays in Chiral Perturbation Theory with Resonances

R. Escribano, S. González-Solís, P. Roig

We have studied the ${\tau }^{-}\to K^{-}{\eta }^{(\prime )}{\nu }_{\tau }$ decays within Chiral Perturbation Theory including resonances as explicit degrees of freedom. We have considered three different for…
