论文摘要
在这项工作中，我们研究了3-3-1模型的有效版本，其中粒子含量与2HDM相同。我们表明，来自$ su（3）_c \ otimes su（3）_l \ otimes u（1）_x $ gauge组具有一系列后果，最相关的是对中性标量的质量的预测或低于电荷标量的质量的预测。给定当前从对撞机搜索，B物理学以及理论约束（诸如四分之一耦合的扰动性和标量势能稳定性）等理论约束中的限制，我们发现新标量不能比350 GEV更轻。
In this work we study an effective version of the 3-3-1 model, in which the particle content is the same of the 2HDM. We show that the inherited structure from the $SU(3)_C \otimes SU(3)_L \otimes U(1)_X$ gauge group has a series of consequences, the most relevant one being the prediction of the masses of the neutral scalar to be of the order or lower than the mass of the charged scalar. Given current constraints from collider searches, B-physics, as well as theoretical constraints such as perturbativity of quartic couplings and stability of the scalar potential, we find that the new scalars cannot be lighter than 350 GeV.
