Probing the effects of Lorentz-symmetry violating Chern-Simons and Ricci-Cotton terms in higher derivative gravity

Abstract: The combined effects of the Lorentz-symmetry violating Chern-Simons and Ricci-Cotton actions are investigated for the Einstein-Hilbert gravity in the second-order formalism modified by higher derivative terms, and their consequences on the spectrum of excitations are analyzed. We follow the lines of previous works and build up an orthonormal basis of projector-like operators for the degrees of freedom, rather than for the spin modes of the fields. With this new basis, the attainment of the propagators is remar… Show more

“…It was shown that a timelike vector of v c = (µ, 0) did not provide any massive mode, leaving massless graviton with 2 DOF, while a spacelike vector v c = (0, v) yielded a massive graviton with 5 DOF [17]. However, the authors [18] have…”
