论文摘要
我们研究了四个维度的相结构（4）不变的晶格希格斯 - 朗瓦型模型，其中包括四个与实际标量场相互作用的交错的费米子。费米子属于对称群的基本表示，而三个标量场的组件在SO的自动划分表示中转换（4）。我们探索了相图，并找到了一个相位之间连续过渡的证据，在该相位无质量到fermions获得质量的相位。该过渡与对称破坏无关，并且没有明显的局部顺序参数。
We investigate the phase structure of a four dimensional SO(4) invariant lattice Higgs-Yukawa model comprising four reduced staggered fermions interacting with a real scalar field. The fermions belong to the fundamental representation of the symmetry group while the three scalar field components transform in the self-dual representation of SO(4). We explore the phase diagram and find evidence of a continuous transition between a phase where the fermions are massless to one where the fermions acquire mass. This transition is not associated with symmetry breaking and there is no obvious local order parameter.
