论文摘要
我们研究了3和4个时空维度中的两种不同的SU（2）量标理论。首先，我们关注的是3维SU（2）理论，其中伴随表示中具有多个希格斯字段，可以将其映射到凝结物理学中的铜酸盐系统中，这些物理物质具有丰富的相图，其中包括高-TC超导性。已经提出，具有4个伴随Higgs字段的理论可用于解释广泛参数的孔掺杂的物理。我们在理论的相图上显示了探索性结果。 另一方面，我们对具有2组基本标量（HIGGS）字段的4个维理论感兴趣，这与2个Higgs Doublet模型（2HDM）相关，这是粒子物理标准模型的拟议扩展。目的是在零温度和有限温度下的电动eak相变时了解该理论的粒子谱。我们介绍了该理论的规模设置和多参数相图的探索性结果。
We study two different SU(2) gauge-scalar theories in 3 and 4 spacetime dimensions. Firstly, we focus on the 3 dimensional SU(2) theory with multiple Higgs fields in the adjoint representation, that can be mapped to cuprate systems in condensed matter physics which host a rich phase diagram including high-Tc superconductivity. It has been proposed that the theory with 4 adjoint Higgs fields can be used to explain the physics of hole-doped cuprates for a wide range of parameters. We show exploratory results on the phase diagram of the theory. On the other hand, we are interested in the 4 dimensional theory with 2 sets of fundamental scalar (Higgs) fields, which is relevant to the 2 Higgs Doublet Model (2HDM), a proposed extension to the Standard Model of particle physics. The goal is to understand the particle spectrum of the theory at zero temperature and the electroweak phase transition at finite temperature. We present exploratory results on scale setting and the multi-parameter phase diagram of this theory.
