WWGENPV 2.0 — A Monte Carlo event generator for four-fermion production at e + e − colliders

Abstract
The Monte Carlo program WWGENPV, designed for computing distributions and generating events for four-fermion production in e^+ e^-collisions, is described. The new version, 2.0, includes the full set of the electroweak (EW) tree-level matrix elements for double-and single-W production, initial-and final-state photonic radiation including PT/PL effects in the Structure Function formalism, all the relevant non-QED corrections (Coulomb correction, naive QCD, leading EW corrections). An hadroni...

Title of program: WWGENPV 2.0
Catalogue Id: ADBU_v2_0 [ADEL]

Nature of problem
The precise measurement of the W-boson mass MW constitutes a primary task of the forthcoming experiments at the high energy electron-positron collider LEP2 (2MW <= sqrt(s) <= 210 GeV). A meaningful comparison between theory and experiment requires an accurate description of the fully exclusive processes e+e- -> 4f, including the main effects of radiative corrections, with the final goal of providing predictions for the distributions measured by the experiments.

摘要
本工作详述了用于计算正负电子碰撞中四费米子产生过程的运动学分布并生成事例的蒙特卡洛（Monte Carlo）程序WWGENPV。其2.0新版本纳入了双W与单W玻色子产生所需的全套电弱（EW）树级矩阵元，包含结构函数（Structure Function）形式体系下考虑PT/PL效应的初态与末态光子辐射，以及所有相关非量子电动力学（QED）修正（库仑修正、朴素量子色动力学、领头阶电弱修正）。原文档此处截断为"An hadroni..."。

## 程序名称：WWGENPV 2.0
## 目录编号：ADBU_v2_0 [ADEL]

## 问题背景
W玻色子质量MW的精确测量，是未来高能正负电子对撞机LEP2（质心系能量区间2MW ≤ √s ≤ 210 GeV）实验的核心任务之一。实现理论与实验的有效比对，需对e⁺e⁻→4f这一全排他性过程开展精准描述，纳入辐射修正的主要效应，最终目标是为实验测得的各类分布提供可靠的理论预言。
