论文摘要
在Electroweak理论的框架内，我们研究了弹性散射过程$ e^{ - } +ν_μ\ rightArrow e^{ - } +ν_μ$在存在强烈椭圆形的激光场的情况下。我们使用第一个诞生的近似值和dirac-volkov状态来描述事件和散射电子的旋转差差横截面的分析表达。我们的结果将bai \ textit {et al。} [phys。 Rev. a \ textbf {85}，013402（2012）]，对于El Asri \ textit {et al。} [phys。修订版D \ textbf {104}，113001（2021）]。我们发现，线性极化的差分横截面显着增强，并减少了圆形和椭圆极化。
Within the framework of electroweak theory, we investigate the elastic scattering process $ e^{-} + ν_μ \rightarrow e^{-} + ν_μ$ in the presence of an intense elliptically polarized laser field. We derive an analytical expression for the spin-unpolarized differential cross section using the first Born approximation and the Dirac-Volkov states to describe the incident and scattered electrons. Our results generalize those found for the linearly polarized field by Bai \textit{et al.} [Phys. Rev. A \textbf{85}, 013402 (2012)] and for the circularly polarized field by El Asri \textit{et al.} [Phys. Rev. D \textbf{104}, 113001 (2021)]. We find that the differential cross section is significantly enhanced for linear polarization and reduced for circular and elliptical polarizations.
