基于先前开发的用于将数据输入纳入蒙特卡洛代码中圈过程的色散QED(disperon QED)方法,我们在次领头阶(NLO)计算了$ee\to\pi\pi\gamma$过程,并在物理合理的所有区域内,采用形状因子标量QED近似引入了π介子矢量形状因子。通过同时考虑形状因子标量QED方法适用性较差的超出项贡献,我们针对选定的实验场景获得了相关理论不确定性的认知。所有计算均在蒙特卡洛框架McMule中实现并公开可用。
英文摘要
Based on the previously developed disperon QED method for incorporating data input into loop processes in Monte Carlo codes, we calculate $ee\toππγ$ at NLO and include the pion vector form factor within the form-factor scalar QED approximation wherever it is physically justified. By also considering contributions beyond, for which the form-factor scalar QED approach is less well justified, we gain insight into the associated theory uncertainty for selected experimental scenarios. All calculations are implemented and made available within the Monte Carlo framework McMule.
