论文摘要
两个HIGGS双重模型预测了3个不同的域壁解决方案的出现，这是由于3个意外的全局对称性（$ z_2 $，cp1和cp2）在电气量表上出现的，用于模型参数的特定选择。在所有三种情况下，我们向场方程介绍了数值扭结解决方案，以及（2+1）和（3+1）维度中模型的动态模拟。对于每个纠结解决方案，我们定义相关的拓扑电流。在所有三种情况下，模拟产生了一个域壁网络，该网络偏离了Minkowski和FRW模拟中的功率定律缩放。这种偏差归因于我们模拟中域壁周围的electroweak组参数的缠绕。我们观察到局部违反了模拟中域壁上的中性真空状况。这种违规归因于整个域壁上的相对电动电动转换，这是从随机初始条件中浮出水面的一般特征。
The Two Higgs Doublet Model predicts the emergence of 3 distinct domain wall solutions arising from the breaking of 3 accidental global symmetries, $Z_2$, CP1 and CP2, at the electroweak scale for specific choices of the model parameters. We present numerical kink solutions to the field equations in all three cases along with dynamical simulations of the models in (2+1) and (3+1) dimensions. For each kink solution we define an associated topological current. In all three cases simulations produce a network of domain walls which deviates from power law scaling in Minkowski and FRW simulations. This deviation is attributed to a winding of the electroweak group parameters around the domain walls in our simulations. We observe a local violation of the neutral vacuum condition on the domain walls in our simulations. This violation is attributed to relative electroweak transformations across the domain walls which is a general feature emerging from random initial conditions.
