Lorentz violations and Euclidean signature metrics

AuthorsBarbero González, Jesús Fernando ; Villaseñor, Eduardo J. S.

CitationPhysical Review D - Particles, Fields, Gravitation and Cosmology 68: 087501 (2003)
AbstractWe show that the families of effective actions considered by Jacobson et al. to study Lorentz invariance violations contain a class of models that represent pure general relativity with a Euclidean signature. We also point out that some members of this family of actions preserve Lorentz invariance in a generalized sense. © 2003 The American Physical Society.
