高精度轻子-核子散射实验的解释需要高阶辐射校正的知识。我们提出了一种计算非极化轻子-质子散射截面的方法，包括二阶轻子辐射校正，包括一环和双环校正，一光子和两光子的辐射以及一光子辐射的一环校正。给出了计划在美因茨MESA设施进行的P2实验的数值结果，并讨论了Qweak和建议的MUSE实验的一些结果。
The interpretation of high-precision lepton-nucleon scattering experiments requires the knowledge of higher-order radiative corrections. We present a calculation of the cross section for unpolarized lepton-proton scattering including leptonic radiative corrections up to second order, including one- and two-loop corrections, radiation of one and two photons and one-loop corrections for one-photon radiation. Numerical results are given for the planned P2 experiment at the MESA facility in Mainz, and some results are also discussed for Qweak and the suggested MUSE experiment.
