A potential for the vertex and self-energy correction is derived from the first-order Born theory. The inclusion of this potential in the Dirac equation, together with the Uehling potential for vacuum polarization, allows for a nonperturbative treatment of these QED effects within the phase-shift analysis. Investigating the 12C and 208Pb targets, a considerable deviation of the respective cross-section change from the Born results is found, which becomes larger with increasing momentum transfer. Estimates for the correction to the beam-normal spin asymmetry are also provided. For the 12C nucleus, dispersion effects are considered as well.

Nuclear form factor, validity of the equivalent photon approximation and Coulomb corrections to muon pair production in photon-nucleus and nucleus-nucleus collisions
应用重子电荷和能量动量的精确QCD求和规则，我们证明了如果核子是核波函数的唯一自由度，则核的结构函数将是在相同的Bjorken x = AQ^2/2（p_Aq）0.05处核子分布的加和< 0.5 up to very small Fermi motion corrections if x>.因此，EMC比与1的差异揭示了原子核中存在非核子自由度。利用精确的QCD求和定则，我们证明了实验研究中所用的比值R_A（x_p，Q_2），其中x_p = Q_2/2q_0m_p，即使在一个核只由小动量核子组成的情况下，也偏离1。与x_p图相比，使用Bjorken x图可使R_A（x，Q^2）进一步减小。核库仑场的洛伦兹变换明确地给出了等效光子对核部分子波函数光子分量的相干贡献。对于A~200，光子携带原子核光动量的~0.0065部分，这几乎补偿了数据分析在Bjorken x和x_p方面的差异。直接观测原子核中大的、主要是核子的短程关联，对x>0.6的EMC效应的大多数模型提出了严重的挑战。这些数据与强子EMC效应反映核子间相互作用的涨落的情形是一致的，这种涨落是由于相互作用核子中颜色分布的涨落引起的。这种情况的动态实现是这样的模型，其中x > 0.5的3q（3qg）组态与附近核子的相互作用较弱，导致抑制这种组态，从而给出正确的EMC效应。展望了未来的研究方向和挑战性问题。
