论文摘要
我们提出了一种新的方法，可以实验确定质子上双重化合物康普顿散射的高能低能结构常数。这种经验确定将减少对Muonic氢羊羔移位的耐药校正估计的理论模型误差。我们证明，在$ e^ - p \至e^ - p \，e^ - e^+$过程中，可以在电子散射设施上访问的di-lepton向前不对称，迄今为止可以在电子散射设施上访问的过程非常敏感性。
We propose a new way to experimentally determine the subleading low-energy structure constant of doubly-virtual Compton scattering on a proton. Such empirical determination will reduce the theoretical model error in estimates of the hadronic correction to the muonic hydrogen Lamb shift. We demonstrate that the di-lepton forward-backward asymmetry in the $e^- p \to e^- p \, e^- e^+$ process, which can be accessed at electron scattering facilities, yields a large sensitivity to this so far unknown low-energy constant.
