# Modified gravity via spontaneous symmetry breaking

@article{Gripaios2004ModifiedGV, title={Modified gravity via spontaneous symmetry breaking}, author={Ben Gripaios}, journal={Journal of High Energy Physics}, year={2004}, volume={2004}, pages={069-069} }

We construct effective field theories in which gravity is modified via spontaneous breaking of local Lorentz invariance. This is a gravitational analogue of the Higgs mechanism. These theories possess additional graviton modes and modified dispersion relations. They are manifestly well-behaved in the UV and free of discontinuities of the van Dam-Veltman-Zakharov type, ensuring compatibility with standard tests of gravity. They may have important phenomenological effects on large distance scales…
