In this paper, we investigate the charged Higgs boson decay in the context of the type-II two-Higgs-doublet model in the presence of a circularly polarized electromagnetic field of laser radiation. The calculations are performed by adopting the Furry picture approach of non-perturbative interactions with the external electromagnetic field. Using the method of exact solutions for charged particles states in the presence of a circularly polarized electromagnetic wave field and evaluating the S-matrix elements, an exact analytic expression is derived for the decay width of leptonic, hadronic and bosonic decay modes. The branching ratios of different decay modes with multiple photon emission and absorption from the laser beam are analyzed and found to be dramatically modified in the region of superstrong fields. The dependencies of the decay width on the laser field strength and frequency are also examined. The results obtained may be interesting for future experimental and theoretical investigations.

在本文中，我们在存在激光辐射的圆极化电磁场的情况下，在 II 型双希格斯双峰模型的背景下研究带电希格斯玻色子衰变。通过采用与外部电磁场的非微扰相互作用的Furry图片方法进行计算。使用圆极化电磁波场存在下带电粒子状态的精确解法并评估S-矩阵元素，推导出轻子、强子和玻色子衰变模式的衰变宽度的精确解析表达式。分析了具有来自激光束的多个光子发射和吸收的不同衰减模式的分支比，发现在超强场区域中发生了显着改变。还检查了衰减宽度对激光场强和频率的依赖性。获得的结果可能对未来的实验和理论研究很有意义。
