Impact of Lorentz violation on anomalous magnetic moments of charged leptons
Andreas Crivellin, Fiona Kirk, Marco Schreck
We address the question whether a violation of Lorentz symmetry can explain the tension between the measurement and the Standard-Model prediction of the anomalous magnetic moment o…
Lorentz-violating electrodynamics in continuous matter
Manoel M. Ferreira, Pedro D. S. Silva, Marco Schreck
We review the propagation of electromagnetic waves in continuous matter in the presence of Lorentz-violating terms. First, we briefly discuss classical electrodynamics with regard…
Cosmology in the presence of diffeomorphism-violating, nondynamical background fields
Carlos M. Reyes, Marco Schreck, Alex Soto
We consider diffeomorphism violation, which is parameterized by nondynamical background fields of the gravitational Standard-Model Extension (SME), and study its effects on the tim…
Modified-gravity theories with nondynamical background fields
Carlos M. Reyes, Marco Schreck
We study the dynamics of a modified-gravity theory, which is supplemented by an extended Gibbons-Hawking-York boundary term and incorporates diffeomorphism violation through nondyn…
