Electron stability constrains neutrino time delays
Mauricio Bustamante, José Manuel Carmona, José Luis Cortés +2
Superluminal neutrino propagation, induced by Lorentz-invariance violation (LIV), is strongly constrained by vacuum pair emission, , a process ordinarily forbidd…
Uncertainties in Constraints from Pair Production on Superluminal Neutrinos
J. M. Carmona, J. L. Cortes, D. Mazon
The use of the vacuum lepton pair production process (), a viable reaction for superluminal neutrinos, to put constraints on Lorentz violations requires a dynamical…
Does a relativistic metric generalization of Newtonian gravity exist in 2+1 dimensions?
J. L. Alonso, J. L. Cortes, V. Laliena
It is shown that, contrary to previous claims, a scalar tensor theory of Brans-Dicke type provides a relativistic generalization of Newtonian gravity in 2+1 dimensions. The theory…
Infrared and ultraviolet cutoffs of quantum field theory
J. M. Carmona, J. L. Cortes
Quantum gravity arguments and the entropy bound for effective field theories proposed in PRL 82, 4971 (1999) lead to consider two correlated scales which parametrize departures fro…
Instanton-like Excitations in 2D Fermionic Field Theory
J. L. Cortes, J. Gamboa, I. Schmidt +1
New non-perturbatives excitations in the massless Thirring and Schwinger models are discussed.
Effective Field Theory of Gravity, Reduction of Couplings and the Renormalization Group
Mario Atance, José Luis Cortés
The structure of the renormalization group equations for the low energy effective theory of gravity coupled to a scalar field is presented. An approximate solution to these equatio…
