HERWIG是一个通用的蒙特卡罗事件发生器，它包括硬轻子-轻子、轻子-强子、强子-强子散射和软强子-强子碰撞的模拟。它使用了初始状态和最终状态QCD辐射的部分阵雨方法，包括喷流内部和喷流之间的颜色相干效应和方位相关性。本文更新了1992年出版的HERWIG描述，强调了自那时以来合并的新功能。其中包括，特别是一阶矩阵元素与部分子簇的匹配，对重夸克衰变的更正确的处理，以及广泛的新过程，包括许多由最小超对称标准模型预测的，带有r宇称违反选项。同时，我们对HERWIG的物理基础进行了简要的回顾，并详细介绍了输入和控制参数以及输出数据，为该程序的潜在用户提供了一个独立的指南。
HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initialand final-state QCD radiation, including colour coherence effects and azimuthal correlations both within and between jets. This article updates the description of HERWIG published in 1992, emphasising the new features incorporated since then. These include, in particular, the matching of first-order matrix elements with parton showers, a more correct treatment of heavy quark decays, and a wide range of new processes, including many predicted by the Minimal Supersymmetric Standard Model, with the option of R-parity violation. At the same time we offer a brief review of the physics underlying HERWIG, together with details of the input and control parameters and the output data, to provide a self-contained guide for prospective users of the program.
