The two-body leptonic decays of both light and heavy-charged mesons \(X_{l2}^{\pm }\) are investigated in the first Born approximation in the presence of a monochromatic and circularly polarized laser field. As a result of using Volkov functions, the analytic study of these processes has brought a change in the parameters associated with each decay process. The decay width, lifetime, and branching ratio of each decay process are affected by increasing the classical parameter \(\xi\) of the meson. A comparison between the matter decay \(X^{+}_{l2}\) and that of the anti-matter \(X^{-}_{l2}\) in the presence of a circularly polarized laser wave, indicates that increasing laser field strength (increasing the classical parameter \(\xi\) ) can induce a slight dominance of matter over antimatter or vise versa.

在单色和圆偏振激光场存在的情况下，在第一玻恩近似中研究了轻介子和重介子\(X_{l2}^{\pm }\)的二体轻子衰变。由于使用了沃尔科夫函数，对这些过程的分析研究带来了与每个衰变过程相关的参数的变化。每个衰变过程的衰变宽度、寿命和分支比都受到介子经典参数\(\xi\)的影响。在圆偏振激光波存在的情况下，物质衰变\(X^{+}_{l2}\)与反物质衰变\(X^{-}_{l2}\)之间的比较表明增加激光场强度（增加经典参数\(\xi\)）可以引起物质相对反物质的轻微优势，反之亦然。
