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…
Duality for massive spin two theories in arbitrary dimensions
B. Gonzalez, A. Khoudeir, R. Montemayor +1
Using the parent Lagrangian approach we construct a dual formulation, in the sense originally proposed by Curtright and Freund, of a massive spin two Fierz-Pauli theory in arbitrar…
Quantization of the Myers-Pospelov model: a progress report
C. M. Reyes, L. Urrutia, J. D. Vergara
The Myers-Pospelov (MP) model is an effective field theory, including dimension five operators, which describes the phenomenology of active Lorentz invariance violation produced by…
