摘要：

本博士论文利用包含共振场的手征拉格朗日量研究了τ轻子的一些强子和辐射衰变。在理论介绍之后，分析了$(πππ)^-$、$(KKπ)^-$、$η^{(\prime)} π^- π^0$强子态和$τ\to (π/K)^- γν_tau$的衰变.对3 π介子模的结构函数分析，三介子模中微分衰变宽度与两粒子不变质量的关系，以及对$τ\to$ η^{（\prime）} π^- π^0 ν_τ $ processes within a single-angle mixing scheme for the $ η $ and $ η^ \prime $介子的简化研究，也作了讨论。

英文摘要：

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 $(πππ)^-$, $(KKπ)^-$ and $η^{(\prime)} π^- π^0$ hadronic states and $τ\to (π/K)^- γν_tau$ 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 $τ\to$η^{(\prime)} π^- π^0 ν_tau$ processes within a single-angle mixing scheme for the $η$ and $η^\prime$ mesons.
