Hadronic and radiative decays of the tau lepton

Abstract

This PhD thesis studies some hadronic and radiative decays of the tau lepton using a Chiral Lagrangian including resonance fields. After a theoretical introduction, the decays to the $(\pi \pi \pi {)}^{-}$, $(KK\pi {)}^{-}$ and ${\eta }^{(\prime )}{\pi }^{-}{\pi }^0$ hadronic states and $\tau \to (\pi /K{)}^{-}\gamma {\nu }_{t}au$ are analysed. Some material, which was not included in the corresponding references, is also discussed: The structure functions analysis for the 3 pion modes, the differential decay width as a function of the two-particle invariant masses in the considered three-meson modes and a simplified study of the $\tau \to$η^{(\prime)} π^- π^0 ν_tau$processeswithinasingle-anglemixingschemeforthe$η$and$η^\prime$ mesons.
