UNIBAB, version 2.0: Monte Carlo event generation for large angle Bhabha scattering at LEP

Abstract This paper describes version 2.0 of the Monte Carlo event generator UNIBAB for Bhabha scattering at LEP/SLC. UNIBAB includes higher order electromagnetic radiative corrections and the effects of soft photon exponentiation explicitly. Weak corrections are included through the use of an electroweak library. Title of program: UNIBAB, Version 2.0 Catalogue Id: ACTC_v1_0 Nature of problem Higher order leading logarithmic QED radiative corrections to large angle Bhabha scattering (e+e- -> e+e-gamma...) at Zo-energies including weak corrections. Versions of this program held in the CPC repository in Mendeley Data ACTC_v1_0; UNIBAB, Version 2.0; 10.1016/0010-4655(94)90188-0 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)摘要 本文介绍了适用于大型电子正电子对撞机（Large Electron-Positron Collider, LEP）与斯坦福线性对撞机（Stanford Linear Collider, SLC）环境下Bhabha散射（Bhabha scattering）的蒙特卡洛事件发生器UNIBAB的2.0版本。UNIBAB显式纳入了高阶电磁辐射修正与软光子指数化效应，并通过调用电弱理论库引入了弱修正。 程序名称：UNIBAB，版本2.0 目录编号：ACTC_v1_0 问题本质 针对Z玻色子能级下的大角度Bhabha散射（e⁺e⁻ → e⁺e⁻γ……）的高阶领头对数量子电动力学（Quantum Electrodynamics, QED）辐射修正，并包含弱修正。 Mendeley数据中的计算机物理学报（Computer Physics Communications, CPC）库收录的本程序版本： ACTC_v1_0; UNIBAB, 版本2.0; 10.1016/0010-4655(94)90188-0 本程序源自贝尔法斯特女王大学所维护的CPC程序库（1969-2019年）
