Title: "Invariant conserved currents in gravity theories with local Lorentz
and diffeomorphism symmetry"
Abstract:
We discuss conservation laws for gravity theories invariant under general
coordinate and local Lorentz transformations. We propose a general
definition of invariant conserved for these theories. We show that every
vector field generates, in any spacetime dimension, for any Lagrangian of
gravitational plus matter fields and for any (minimal or nonminimal) type of
interaction, an invariant conserved current, which can be written on-shell
in terms of an invariant superpotential. We apply the general method to
compute the total energy and angular momentum of exact solutions in several
gravitational models.
