On the Possibility of Superluminal Neutrino Propagation
Jean Alexandre, John Ellis, Nick E. Mavromatos
We analyze the possibility of superluminal neutrino propagation delta v = (v - c)/c > 0 as indicated by OPERA data, in view of previous phenomenological constraints from supernova…
Lifshitz-type Quantum Field Theories in Particle Physics
Jean Alexandre
This introduction to Lifshitz-type field theories reviews some of its aspects in Particle Physics. Attractive features of these models are described with different examples, as the…
A Lorentz-Violating Alternative to Higgs Mechanism?
Jean Alexandre, Nick E. Mavromatos
We consider a four-dimensional field-theory model with two massless fermions, coupled to an Abelian vector field without flavour mixing, and to another Abelian vector field with fl…
Spherically symmetric solutions, Newton's Law and IR limit λ->1, in Covariant Horava Lifshitz Gravity
Jean Alexandre, Pavlos Pasipoularides
In this note we examine whether spherically symmetric solutions in Covariant Horava Lifshitz Gravity can reproduce Newton's Law in the IR limit λ->1. We adopt the position that the…
Mass Hierarchies in Lorentz-Violation-induced Dynamical Mass Models
Jean Alexandre, Nick E. Mavromatos
We discuss the issue of fermion mass hierarchies between lepton and quark families in toy models of dynamical generation of fermion masses through minimal Lorentz Invariance Violat…
Properties of a consistent Lorentz-violating Abelian gauge theory
Jean Alexandre, Ariadni Vergou
A Lorentz violating modification of massless QED is proposed, with higher order space derivatives for the photon field. The fermion dynamical mass generation is studied with the Sc…
