论文摘要
考虑在外部常数交叉电磁场中通过光子创建带电的无质量费米子对。为此，我们将光子的弹性散射振幅（EAS）的表达在较早获得的大规模量子电动力学的一环近似中，并计算其无质量极限。我们假设光子EAS的假想部分描述了在外部电磁场中产生带电的无质量费米对的总概率。还在恒定的交叉电磁场中研究了带电的无质量费米的光子发射。我们获得了光子发射的总概率，该光子发射计算在无质量极限的电磁场中带电大量费米的弹性散射幅度。
Creation of charged massless fermion pair by a photon in external constant crossed electromagnetic field is considered. For this we use the expression of elastic scattering amplitude (EAS) of photon in the one-loop approximation of massive quantum electrodynamics obtained earlier and calculate its massless limit. We assume that the imaginary part of EAS of photon describes the total probability of charged massless fermion pair creation in external electromagnetic field. Photon emission by a charged massless fermion is also studied in constant crossed electromagnetic field. We obtain the total probability of photon emission calculating elastic scattering amplitude of charged massive fermion in the electromagnetic field in the massless limit.
