论文摘要
我们提出了一个新的蒙特卡洛生成器，{\ tt ee $ \ in $ mc}，以模拟$ e^{+} Lepton衰变适用于$ e^{+} e^{ - } $ colleders从阈值到$ \ sim 10.58Gev $的能量。 $ e^{+}辐射真空极化。在Yennie-Frautschi-Suura凸起形式上研究了红外差异，其中使用了几种众所周知的近似值和基于对软和虚拟光子的确切贡献的制定。 $τ$ Lepton的仿真由出生级别的松弛衰减模式和基于通量管破坏模型和手性共振Lagrangian模型的理论模型以及大多数半级衰减模式的实验模型。这包括用于研究$τ$ Lepton的衰减中低质量标量扇区的起源的HADRONIC模型，并通过手性对称性破裂的腐烂及其与组成Quark质量质量的起源有关。
We present a new Monte-Carlo generator, {\tt ee$\in$MC}, for the simulation of $e^{+}e^{-} \to μ^{+} μ^{-} (γ) $, $e^{+}e^{-} \to τ^{+}τ^{-} (γ) $ and $τ$ lepton decays which is suitable for $e^{+}e^{-}$ colliders from threshold up to energy of $\sim 10.58GeV$. The $e^{+}e^{-} \to μ^{+} μ^{-}(γ) $, $e^{+}e^{-} \to τ^{+}τ^{-}(γ)$ interactions are computed up to the exact LO matrix element where the running of $α_{QED}$ includes both the LO leptonic and hadronic vacuum polarization. Infra-red divergences are investigated within the Yennie-Frautschi-Suura Exponentiation formalism, where several well-known approximations and a formulation based on the exact LO contribution to the soft and virtual photons are applied. The simulation of the $τ$ lepton consists of the leptonic decay modes at Born level and theoretical models based on Flux-Tube Breaking Models and Chiral Resonance Lagrangian Models as well as experimental models for the majority of semi-leptonic decay modes. This includes hadronic models for investigating the origin of low mass scalar sector recently observed in decays of the $τ$ lepton and their association with the origin of the constituent-quark mass through Chiral-symmetry Breaking.
