# Unification of gravity, gauge fields and Higgs bosons

@article{Lisi2010UnificationOG, title={Unification of gravity, gauge fields and Higgs bosons}, author={Arianna Lisi and Lee Smolin and Simone Speziale}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2010}, volume={43}, pages={445401} }

We consider a diffeomorphism invariant theory of a gauge field valued in a Lie algebra that breaks spontaneously to the direct sum of the spacetime Lorentz algebra, a Yang–Mills algebra and their complement. Beginning with a fully gauge invariant action—an extension of the Plebanski action for general relativity—we recover the action for gravity, Yang–Mills and Higgs fields. The low-energy coupling constants, obtained after symmetry breaking, are all functions of the single parameter present in…
