论文摘要
我们在两个HIGGS模型有效场理论（2HDMEFT）的框架中构建了意外的对称电位，包括维度6和Dimension 8的高阶操作员。我们的构建是通过基于Prime不变性的较早开发的技术来促进的。此外，我们采用了一种替代方法，该方法利用双方表示中的每个对称性的发电机，并展示如何使用该方法来识别任何更高维度的运算符。意外的对称2HDMEFT电位表现出两类的对称性：（i）连续对称性和（ii）离散对称性。 2hdmeft中的连续对称性数与2HDM相同。但是，引入高阶操作员允许其他高阶离散对称性，例如$ z_n $和cp $ n $。我们对2HDMEFT中的17个意外对称性的完整列表进行了分类，包括尺寸-6和Dimension-8运算符，并得出了控制相应有效电位的理论参数的关系。
We construct accidentally symmetric potentials in the framework of Two Higgs Model Effective Field Theory (2HDMEFT) including higher-order operators of dimension 6 and dimension 8. Our construction is facilitated by an earlier developed technique based on prime invariants. In addition, we employ an alternative method that utilises the generators of each symmetry in the bi-adjoint representation and show how this method can be used to identify operators of any higher dimension. The accidentally symmetric 2HDMEFT potentials exhibit two classes of symmetries: (i) continuous symmetries and (ii) discrete symmetries. The number of continuous symmetries in the 2HDMEFT remains the same as in the 2HDM. However, the introduction of higher-order operators allows additional higher-order discrete symmetries, such as $Z_n$ and CP$n$. We classify the full list of the 17 accidental symmetries in the 2HDMEFT including dimension-6 and dimension-8 operators, and derive the relations that govern the theoretical parameters of the corresponding effective potentials.
