Observables in theories with a varying fine structure constant. (English) Zbl 1329.85008
Summary: We show how two seemingly different theories with a scalar multiplicative coupling to electrodynamics are actually two equivalent parametrisations of the same theory: despite some differences in the interpretation of some phenomenological aspects of the parametrisations, they lead to the same physical observables. This is illustrated on the interpretation of observations of the cosmic microwave background.
