We consider extra dimensional gauge theories on an interval. We first review the derivation of the consistent boundary conditions (BC’s) from the action principle. These BC’s include choices that give rise to breaking of the gauge symmetries. The boundary conditions could be chosen to coincide with those commonly applied in orbifold theories, but there are(More)
We present a 5D gauge theory in warped space based on a bulk SU(2)L x SU(2)R x U(1)(B-L) gauge group where the gauge symmetry is broken by boundary conditions. The symmetry breaking pattern and the mass spectrum resemble that in the standard model (SM). To leading order in the warp factor the rho parameter and the coupling of the Z (S parameter) are as in(More)
Multiple system atrophy (MSA) is a disease causing parkinsonism in which response to levodopa is classically absent, poor, or transient. Idiopathic Parkinson's disease (IPD) itself, which responds favorably to levodopa, has been associated with the development of disease-related depression. Over and above the clinical and pathological characteristics of(More)
The psychiatric complications of epilepsy are varied but may be considered under two main groups--those directly related to ictal activity and those that occur during the inter-ictal period. Epilepsy and psychiatry are also similar in that they cause a great deal of social difficulties and restriction in terms of activities and employment opportunities(More)
The radion dynamics related to the presence of moving branes with both positive or negative tensions is studied in the linearized approximation. The radion effective Lagrangian is computed for a compact system with three branes and in particular we examine the decompactification limit when one brane is sent to infinity. In the non-compact case we calculate(More)
A phase of massive gravity free from pathologies can be obtained by coupling the metric to an additional spin-two field. We study the gravitational field produced by a static spherically symmetric body, by finding the exact solution that generalizes the Schwarzschild metric to the case of massive gravity. Besides the usual 1/r term, the main effects of the(More)
Theories with an extra spin-two field coupled to gravity admit a massive phase with broken Lorentz symmetry. While the equivalence principle is respected, the Newtonian potentials are in general modified, but they may be protected by a scale symmetry of the coupling term. The gravitational waves phenomenology is quite rich: two gravitons, one massive and(More)
A systematic study of the different phases of Lorentz-breaking massive gravity in a curved background is performed. For tensor and vector modes, the analysis is very close to that of Minkowski space. The most interesting results are in the scalar sector where, generically, there are two propagating degrees of freedom (DOF). While in maximally symmetric(More)
