Light scalars coupled to photons and non-newtonian forces

Abstract

A particle $\varphi$ coupling to two photons couples also to charged particles, like protons, through a loop. If the particle is a light scalar this induced coupling to protons leads to non-newtonian forces. We show that the experimental constraints on exotic, fifth-type forces lead to stringent constraints on the $\varphi \gamma \gamma$ coupling.

With respect to v1, we have extended the paper, also new authors have joined. Submitted to PRL
