Research output: Contribution to journalArticlepeer-review


We consider a new effective symmetry that acts on a gauge invariant Lagrangian. We show that the standard model after spontaneous symmetry breaking is invariant under this symmetry which identifies up to a scale factor the gauge parameter with the elementary or composite scalars in the theory. We discuss some of the consequences of this symmetry in the abelian and non- abelian sectors of the standard model.
