Theoretical constraints on the scalar potential of the compact 341 model with three quadruplets scalar fields are discussed. It is shown that in order to ensure the good behavior of the potential and the viability of the model, the criteria, such as copositivity, minimization, perturbative unitarity, perturbativity of the scalar couplings and no ghost scalar bosons (scalar bosons masses positivity), are imposed and bounds on the scalar couplings are obtained. Moreover, the existence of the Landau pole in the model imposes stringent limits.

紧凑 341 模型中标量参数的理论约束

讨论了具有三个四重标量场的紧凑型 341 模型的标量势的理论约束。结果表明，为了确保势能的良好行为和模型的可行性，标量耦合的共存性、最小化、微扰单一性、微扰性和无鬼标量玻色子（scalar bosons mass positivity）等标准，施加并获得标量耦合的界限。此外，模型中朗道极点的存在施加了严格的限制。
