Radiative Bhabha scattering in special configurations with missing final e+ and/or e-

Abstract
An event generator for radiative Bhabha scattering with missing e^+and/or e^-is developed in electroweak theory. The program can generate events of three configurations, in which single γ, single e and eγ are observed.

Title of program: RABHAT
Catalogue Id: ABLC_v1_0

Nature of problem
In e+e- collision experiments the radiative Bhabha scattering gives one of the most severe backgrounds to other interesting processes. It is very important to estimate the cross section in order to remove this background and obtain physical results. Analysis of actual experimental data also requires simulated four vectors of the process to determine the acceptance of detectors.

摘要
本研究基于电弱理论（electroweak theory），开发了一款针对存在丢失正电子和/或电子的辐射性Bhabha散射（radiative Bhabha scattering）事件产生器。该程序可生成三种构型的事件，分别对应探测到单光子、单电子以及电子-光子（eγ）末态。

程序标题：RABHAT
目录编号：ABLC_v1_0

问题本质
在正电子-电子（e⁺e⁻）碰撞实验中，辐射性Bhabha散射是其他感兴趣物理过程的最显著本底之一。为去除该本底并获取可靠物理结果，精确估算其散射截面至关重要。此外，对实际实验数据的分析还需要该过程的模拟四动量矢量（four vectors），以确定探测器的接收效率。
