Hamiltonian analysis of extra gauge symmetries in an R+T2theory of gravity

Abstract
We study the Hamiltonian structure of a class of gravity Lagrangians which are linear in the curvature and quadratic in the torsion, in the case when extra gauge symmetries are present in the theory. The corresponding symmetry generators are found by using Dirac’s general method for systems with constraints, and the dynamical meaning of extra gauge symmetries is clarified.
