π介子阈下虚康普顿散射的蒙特卡罗模拟
Monte Carlo simulation of virtual Compton scattering below pion threshold
摘要:
本文介绍了蒙特卡罗模拟专门开发的介子阈值以下的介子实验,已在MAMI和JLab进行。该模拟根据(Bethe-Heitler + Born)截面行为生成事件,并考虑所有相关的分辨率恶化效应。它确定了用于精确确定光子电产生绝对截面的各种实验设置的“有效”立体角。
英文摘要:
This paper describes the Monte Carlo simulation developed specifically for the VCS experiments below pion threshold that have been performed at MAMI and JLab. This simulation generates events according to the (Bethe-Heitler + Born) cross section behaviour and takes into account all relevant resolution-deteriorating effects. It determines the `effective' solid angle for the various experimental settings which are used for the precise determination of photon electroproduction absolute cross section.
