摘要

研究了量子电动力学中电子-正电子湮灭过程中单双氘和双氘的产生。在计算轻子产生的振幅和横截面时，考虑了单光子和双光子电子-正电子湮灭的两种机制。我们考虑了与轻子相对动量有关的产生振幅的相对论修正，以及束缚态波函数从静止坐标系到运动参考系的变换规律。

Production of Leptonic Bound States in Electron–Positron Annihilation

We study the production of single dimuonium and ditauonium in electron–positron annihilation in quantum electrodynamics. Two mechanisms of one- and two-photon electron–positron annihilation are taken into account when calculating the amplitudes and cross-sections of leptonia production. We take into account relativistic corrections in the production amplitude connected with the relative momenta of leptons and with the transformation law of the bound state wave function from the rest frame to the moving reference frame.
