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…
Topological field theories in n-dimensional spacetimes and Cartan's equations
Vladimir Cuesta, Merced Montesinos, Mercedes Velazquez +1
Action principles of the BF type for diffeomorphism invariant topological field theories living in n-dimensional spacetime manifolds are presented. Their construction is inspired b…
Space-Time Diffeomorphisms in Noncommutative Gauge Theories
Marcos Rosenbaum, J. David Vergara, L. Roman Juarez
In previous work [Rosenbaum M. et al., J. Phys. A: Math. Theor. 40 (2007), 10367-10382, hep-th/0611160] we have shown how for canonical parametrized field theories, where space-tim…
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…
