The Photon Sector in the Quantum Myers-Pospelov Model: An improved description
C. M. Reyes, L. F. Urrutia, J. D. Vergara
The quantization of the electromagnetic sector of the Myers-Pospelov model coupled to standard fermions is studied. Our main objective is to construct an effective quantum theory t…
Coping with the Pais-Uhlenbeck oscillator's ghosts in a canonical approach
Aldo Déctor, Hugo A. Morales-Técotl, Luis F. Urrutia +1
A {\em complex} canonical transformation is found that takes the fourth order derivative Pais-Uhlenbeck oscillator into two independent harmonic oscillators thus showing that this…
The scalar sector in the Myers-Pospelov model
C. M. Reyes, L. Urrutia, J. D. Vergara
We construct a perturbative expansion of the scalar sector in the Myers-Pospelov model, up to second order in the Lorentz violating parameter and taking into account its higher-ord…
Dimensional reduction as a method to obtain dual theories for massive spin two in arbitray dimensions
A. Khoudeir, R. Montemayor, Luis F. Urrutia
Using the parent Lagrangian method together with a dimensional reduction from to dimensions we construct dual theories for massive spin two fields in arbitrary dimensio…
