Testing Screened Modified Gravity

Long range scalar fields with a coupling to matter appear to violate known bounds on gravitation in the solar system and the laboratory. This is evaded thanks to screening mechanisms. In this short review, we shall present the various screening mechanisms from an effective field theory point of view. We then investigate how they can and will be tested in the laboratory and on astrophysical and cosmological scales.

Automated summary

This article discusses the violation of known bounds on gravitation by long range scalar fields with a coupling to matter, and how this is evaded through screening mechanisms. It further explores how these mechanisms will be tested at different scales in laboratory and astrophysical and cosmological contexts.
