标题： ERATO: event generator for four-fermion production at LEP2 energies and beyond

摘要： 本文是对 ERATO 的详细描述。ERATO 是一个蒙特卡罗事件生成器，用于描述 LEP2 及其以后的四费米子产生过程。所有导致四费米子产生的树图阶过程均被包括，并考虑了所有相关的 QCD 贡献。QED 高阶修正通过结构函数方法引入，而与费米子圈相关的弱修正也包含在内。在研究三线规范耦合时给予了特别关注，所有可能的贡献，包括 CP 破坏项，均已实现。 显示英文摘要

摘要： This paper is a long write-up of ERATO. ERATO is a Monte Carlo event generator describing four fermion production at LEP2 and beyond. All tree-order processes leading to four fermions are included, taking into account all relevant QCD contributions. QED higher order corrections are introduced via a structure function approach, whereas weak corrections related to fermion loops are also included. Special attention has been paid in studying the trilinear gauge couplings, and all possible contributions, including the CP-violating ones, have been implemented.
