We consider the theory of a light conformally coupled scalar field, that is, one that is coupled directly to the Ricci scalar of the gravitational sector. This theory can be written equivalently as one of a light scalar that is coupled to the Standar... Read More about Higgs-induced screening mechanisms in scalar-tensor theories.
