Differentiating dilatons from the axions by their mixing with photons
Abstract The quanta of scalar fields like the dilaton ( $$\phi $$ ϕ ) of scale symmetry origin and those of pseudoscalar fields like the axion ( $$\phi '$$ ϕ ′ ) of Peccei–Quinn symmetry origin couple to di-photons through dimension-5 operators. In a magnetized medium (MM), they in principle ca...
