Higgs Scalar Fields and Discrete Symmetry

概要
- 論文の詳細を見る
We point out that the Higgs scalar field introduced as a gauge field associated with the Z_2 discrete symmetry plays a role of the gauge transformation function for Yang-Mills fields and for fermion fields. We show that the Higgs potential identically vanishes and the Yukawa couplings between fermions and the Higgs field are gauged away. We are left with a massless fermion and a massive fermion both interacting with the Yang-Mills field. They are exchanged with each other by another massive vector field. We obtain such a massive vector field without the Higgs potential and hence without any spontaneous-symmetry breaking. This phenomenon is specially characteristic in this model.
