我们提出了在大型强子对撞机（LHC）中守恒cp的2-希格斯双重态模型（2HDMs）中轻荷希格斯玻色子搜索的讨论。考虑到所有可用的实验和理论限制，我们回顾了所有可能的过程，这些过程将允许检测到质量低于顶夸克质量的这种粒子。分析了两种不同类型的过程：一种只依赖于tan - β和带电希格斯玻色子质量，因为它只涉及带电希格斯玻色子汤川耦合；另一种依赖于几乎所有的模型参数，主要是由于希格斯自耦合的存在。我们讨论了每一种过程可以覆盖的2HDMs参数空间区域，并定义了在大型强子对撞机上进行实验搜索的一些指导方针。
We present a discussion of light charged Higgs boson searches at the Large Hadron Collider (LHC) in CP-conserving 2-Higgs Doublet Models (2HDMs). Taking into account all available experimental and theoretical constraints we review all possible processes that would allow for a detection of such a particle with a mass below the top quark mass. Two different types of processes are analysed: one that depends only on tan beta and on the charged Higgs boson mass because it involves only the charged Higgs boson Yukawa couplings; the other that depends on almost all model parameters, mainly due to the presence of Higgs self-couplings. We discuss the regions of parameter space of 2HDMs that can be covered be each type of process and define some guidelines for experimental searches at the LHC.
