论文摘要
在（反）Lepton-Proton弹性散射中，硬光子发射对电荷不对称性的影响首次在超过超层次的极限之外评估，同时在计算的所有步骤中保留Lepton质量。该贡献 - 负责电荷不对称的原因是由从麻肉和质子产生的实际光子发射之间的干扰引起的。在计算过程中，未考虑任何中介质子的激发态，从而使我们能够为该粒子使用标准的费米子繁殖物。使用Bardin-Shumeiko的Lorenz-Invariant方法提取的红外发散被两光量交换贡献的相应软部分取消。在杰斐逊实验室测量的运动条件下进行了数值分析，并在PSI中进行了缪斯实验。
The influence of the hard photon emission on the charge asymmetry in the (anti)lepton-proton elastic scattering was evaluated for the first time beyond the ultrarelativistic limit, while retaining the lepton mass at all steps of the calculation. This contribution - responsible for the charge asymmetry - is induced by interference between real photon emission from the lepton and proton. During the calculation any excited states of the intermediated proton are not considered, allowing us to use the standard fermionic propagator for this particle. The infrared divergence extracted using Lorenz-invariant approach of Bardin-Shumeiko is canceled by the corresponding soft part of the two-photon exchange contribution. Numerical analysis was performed within kinematic conditions of Jefferson Lab measurements and MUSE experiment in PSI.
