A mechanism to generate varying speed of light via Higgs-dilaton coupling: theory and cosmological applications
Abstract We probe into a class of scale-invariant actions, which allow the Higgs field $$\Phi $$ Φ to interact with a dilaton field $$\chi $$ χ of the background spacetime through the term $$\chi ^{2}\,\Phi ^{\dagger }\Phi $$ χ 2 Φ † Φ . Upon spontaneous gauge symmetry breaking, the vacuum expectati...
