Chirality in unified theories of gravity
Abstract
We show how to obtain a single chiral family of an SO(10) grand unified theory (GUT), starting from a Majorana-Weyl representation of a unifying (GraviGUT) group SO(3,11), which contains the gravitational Lorentz group SO(3,1). An action is proposed, which reduces to the correct fermionic grand unified theory action in the broken phase.
