On plane wave solutions in Lorentz-violating extensions of gravity
J. R. Nascimento, A. Yu. Petrov, A. R. Vieira
In this paper, we obtain dispersion relations corresponding to plane wave solutions in various Lorentz-breaking extensions of gravity with dimensions 3, 4, 5 and 6. We demonstrate…

Lorentz-Violating Running of Coupling Constants
A. R. Vieira, N. Sherrill
We compute the full vacuum polarization tensor in the minimal QED extension. We find that its low-energy limit is dominated by the radiatively induced Chern-Simons-like term and th…

Lorentz and CPT Violation in Partons
Alan Kostelecky, Enrico Lunghi, Nathan Sherrill +1
A framework is presented for the factorization of high-energy hadronic processes in the presence of Lorentz and CPT violation. The comprehensive effective field theory describing L…
