标题： ee$\in$MC: Comments on Asymmetries in QED

摘要： 在量子电动力学过程$e^{+}e^{-}\to l^{+}l^{-}(n\gamma)$中，存在两个在$cos(\theta)$和$cos(\theta^{*})$分布中已知的角不对称性。 在本文中，针对$cos(\theta^{*})$分布的 QED 角不对称性进行了研究，从构成狄拉克传播子的狄拉克传播子和相关边界条件出发，并探讨了潜在的意义。 显示英文摘要

摘要： In the Quantum Electrodynamics process $e^{+}e^{-}\to l^{+}l^{-}(n\gamma)$, there are two well known angular asymmetries in the $cos(\theta)$ and the $cos(\theta^{*})$ distributions. In this paper, the QED angular asymmetry related to the $cos(\theta^{*})$ distribution is investigated in terms of the Dirac propagator and the associated boundary conditions from which the Dirac propagator is constructed and the potential implications are examined.
