论文摘要
我们提出了{\ tt kkmcee 5.00.2}蒙特卡洛事件发生器，用于Lepton和Quark Pair Producation，用于高能电子脉络膜歼灭过程。它仍然是此类过程中最复杂的事件生成器。它的整个源代码都用现代的C ++语言重写。它重现了Fortran 77中旧\ KKMC \代码的所有功能。但是，还实施了蒙特卡洛算法的许多改进。最重要的是，它旨在成为未来改进的起点，这对于未来的高精度Lepton Collider项目将是必不可少的。与较旧版本一样，除了更高的QED校正外，它还还使用经典{\ tt dizet}库的版本，并使用{\ tt tauola}程序。 {\ tt dizet}和{\ tt tauola}外部库仍在fortran 77中。此外，{\ tt hepmc3}接口与其他MC程序，例如parton淋浴和探测器模拟，取代了较老的{\ tt hepevt} interface。在使用外部{\ tt photos}库中，在$τ$衰减中实现了{\ tt hepmc3}接口。
We present the {\tt KKMCee 5.00.2} Monte Carlo event generator for lepton and quark pair production for the high energy electron-positron annihilation process. It is still the most sophisticated event generator for such processes. Its entire source code is re-written in the modern C++ language. It reproduces all features of the older \kkmc\ code in Fortran 77. However, a number of improvements in the Monte Carlo algorithm are also implemented. Most importantly, it is intended to be a starting point for the future improvements, which will be mandatory for the future high precision lepton collider projects. As in the older version, in addition to higher order QED corrections, it includes so-called \order{α^{1.5}} genuine weak corrections using a version of the classic {\tt DIZET} library and polarized $τ$ decays using {\tt TAUOLA} program. Both {\tt DIZET} and {\tt TAUOLA} external libraries are still in Fortran 77. In addition, a {\tt HEPMC3} interface to other MC programs, like parton showers and detector simulation, replaces the older {\tt HepEvt} interface. The {\tt HEPMC3} interface is also exploited in the implementation of the additional photon final state emissions in $τ$ decays using an external {\tt PHOTOS} library rewritten in C.
