摘要:

在本研究中,我们利用重整化群方程和单标度重整化方法,在单圈层级分析了economical 331模型的真空稳定性。通过积分这些方程,我们确定了直至普朗克标度的稳定性条件,并纳入了近期关于类希格斯新玻色子、带电标量粒子以及带电和中性规范玻色子的实验数据所给出的约束。我们的分析揭示了最重标量粒子质量与奇异夸克质量之间引人关注的关系,以确保该模型直至普朗克标度都保持稳定。对于本工作采用的331能标18 TeV,我们发现了该模型最重夸克质量的一个上限,该上限与未来LHC运行的探测范围相距不远,可作为待搜寻的边界。此外,我们还探究了源自稳定性和微扰性条件的标量耦合之间的关系。这些条件对economical 331模型施加了前所未有的约束。

英文摘要:

In this study, we analyze the vacuum stability of the economical 331 model at the one-loop level using the renormalization group equations and a single-scale renormalization method. By integrating these equations, we determine stability conditions up to the Planck scale, incorporating constraints from recent experimental data on new Higgs-like bosons, charged scalars, and charged and neutral gauge bosons. Our analysis uncovers intriguing relations between the mass of the heaviest scalar and the masses of exotic quarks, in order to ensure stability of the model up to the Planck scale. For the 331 energy scale used in this work, $18$ TeV, we find an upper bound on the heaviest quark mass of the model, which is not so distant from future LHC runs, serving as bounds to be searched. Additionally, we explore relations between the scalar couplings coming stability and perturbativity conditions. These impose unprecedented constraints on the economical 331 model.
