Monte Carlo program KORALW 1.02 for W-pair production at energies with Yennie-Frautschi-Suura exponentiation

Program title: KORALW 1.02
Catalogue ID: ADCT_v1_0

Abstract
The Monte Carlo program KORALW version 1.02 for W-pair production is presented. Its main features are: multiple initial state photonic radiation with finite transverse photon momenta generated according to the Yennie-Frautschi-Suura Monte Carlo technique and massive kinematics for all final particles. Matrix element features second-order leading-logarithmic initial-state QED corrections.

The dedicated semi-analytical program KORWAN, with structure-function based leading-logarithmic initial-state ...

Nature of problem
The W pair production and decay will be used as an important data point for precise tests of the standard electroweak theory at LEP2 and higher energies. The effects due to QED bremsstrahlung and apparatus efficiency have to be subtracted from the data. The program includes also effects of the secondary decays, i.e. hadronization of quarks and tau lepton decays.

摘要
本文介绍了用于W玻色子对产生的蒙特卡洛程序KORALW 1.02版。其核心特性包括：依据Yennie-Frautschi-Suura蒙特卡洛方法生成的、带有有限横向光子动量的初态多光子辐射，以及所有末态粒子的大质量运动学处理。程序的矩阵元包含二阶领头对数近似的初态量子电动力学（QED）修正。
专用半解析程序KORWAN搭载了基于结构函数的初态领头对数近似……

问题描述
W玻色子对的产生与衰变可作为LEP2及更高能区标准电弱理论精确检验的关键观测数据。实验分析中需从观测数据中扣除量子电动力学韧致辐射与探测器效率带来的效应。本程序同时涵盖次级衰变过程的效应，即夸克的强子化以及τ轻子的衰变。
