论文摘要
在质量框架的中心，我们研究了与一对费米子（$ e^{+} e^{ - } \ rightArrow f \ bar {f} h $相关的希格斯生产过程，在强烈的电磁场内的领先顺序与圆形极化。我们的分析计算基于狭窄的宽度近似（NWA），该近似在领先顺序上是有效的。我们仅将激光场中的初始粒子视为第一步。在第二部分中，我们在激光场中嵌入了初始颗粒和最终粒子。在两种情况下，我们都分析了产生的希格斯玻色子的角度分布是激光参数的函数。我们已经发现，在初始颗粒和最终粒子都嵌入激光字段的情况下，该过程的差异横截面的数量级$ e^{+} e^{ - } \rightArrowμ^{+}+}μ^{ - } h $较大，而$ e^e^{+e^e^{+e^{+e^{+e^{+e^{+e^{+e}增强。
In the centre of mass frame, we have investigated the process of Higgs production in association with a pair of fermions, $e^{+}e^{-}\rightarrow f\bar{f} H$, at the leading order inside an intense electromagnetic field with circular polarization. Our analytical calculations are based on the Narrow Width Approximation (NWA), which is valid in the leading order. We have considered only the initial particles inside the laser field as a first step. In the second part, we have embedded both initial and final particles in the laser field. We have analyzed the angular distribution of the produced Higgs boson as a function of the laser parameters in both cases. We have found that in the case where both initial and final particles are embedded in the laser field, the order of magnitude of the differential cross-section of the process $e^{+}e^{-}\rightarrowμ^{+}μ^{-}H$ is reduced more significantly, while that of the process $e^{+}e^{-}\rightarrowν\barνH$ is enhanced.
