Description
A "Chameleon" is a force whose apparent range and strength can depend on the size and density of the source. I discuss how a U(1) gauge force can be chameleonic due to screening from a light charged scalar. Such screening can weaken astrophysical constraints on new gauge bosons, allow a B-L interaction to be strong enough to affect short baseline neutrino oscillations, and change the allowed regions of sterile neutrinos.
