We present a model of gravity based on spontaneous Lorentz symmetry breaking. We start from a model with spontaneously broken symmetries for a massless 2-tensor with a linear kinetic term and a nonderivative potential, which is shown to be equivalent to linearized general relativity, with the Nambu-Goldstone (NG) bosons playing the role of the gravitons. We apply a bootstrap procedure to the model based on the principle of consistent coupling to the total energy energy-momentum tensor… 

Spin-dependent potentials, axion-like particles and Lorentz-symmetry violation: beyond the Standard Model phenomenology at the low-energy frontier of physics

It is well known that the Standard Model is not complete and many of the theories that seek to extend it predict new phenomena that may be accessible in low-energy settings. This thesis deals with



Gravity from spontaneous Lorentz violation

We investigate a class of theories involving a symmetric two-tensor field in Minkowski spacetime with a potential triggering spontaneous violation of Lorentz symmetry. The resulting massless

Gravity from local Lorentz violation

In general relativity, gravitational waves propagate at the speed of light, and so gravitons are massless. The masslessness can be traced to symmetry under diffeomorphisms. However, another elegant

Gravity, Lorentz violation, and the standard model

The role of the gravitational sector in the Lorentz- and CPT-violating standard-model extension ~SME! is studied. A framework is developed for addressing this topic in the context of Riemann-Cartan

Self-interaction and gauge invariance

A simple unified closed form derivation of the non-linearities of the Einstein, Yang-Mills and spinless (e.g. chiral) meson systems is given. For the first two, the non-linearities are required by

Quantization of Einstein's Gravitational Field: General Treatment

The quantization of the complete gravitational field is carried out by extending the work of an earlier paper. The main obstacles in the quantization of Einstein's field are overcome by expressing

$CPT$ violation and the standard model

Spontaneous CPT breaking arising in string theory has been suggested as a possible observable experimental signature in neutral-meson systems. We provide a theoretical framework for the treatment of

Lorentz-Violating Extension of the Standard Model

In the context of conventional quantum field theory, we present a general Lorentz-violating extension of the minimal

Field theories with « Superconductor » solutions

SummaryThe conditions for the existence of non-perturbative type « superconductor » solutions of field theories are examined. A non-covariant canonical transformation method is used to find such

Data Tables for Lorentz and CPT Violation

This work tabulates measured and derived values of coefficients for Lorentz and $CPT$ violation in the standard-model extension. Summary tables are extracted listing maximal attained sensitivities in
