Abstract

While non-action-generated, but identically conserved, abelian/YM gauge vectors exist, they are unsuitable for building alternate field equations, because they have no stress-tensor, hence do not permit Poincare generators and, most physically, cannot consistently couple to gravity. Separately, their geometric analogues, covariantly conserved non-Lagrangian symmetric tensors, probably do not even exist, but their weak field, abelian, counterparts do, and share the vector fields' absence of generators.

Black holes in vector-tensor theories

Journal Article Heisenberg, Lavinia ; Kase, Ryotaro ; Tsujikawa, Shinji ; ... - Journal of Cosmology and Astroparticle Physics

We study static and spherically symmetric black hole (BH) solutions in second-order generalized Proca theories with nonminimal vector field derivative couplings to the Ricci scalar, the Einstein tensor, and the double dual Riemann tensor. We find concrete Lagrangians which give rise to exact BH solutions by imposing two conditions of the two identical metric components and the constant norm of the vector field. These exact solutions are described by either Reissner-Nordström (RN), stealth Schwarzschild, or extremal RN solutions with a non-trivial longitudinal mode of the vector field. We then numerically construct BH solutions without imposing these conditions. For cubic andmore »« less

Non-Abelian gauge field theory in scale relativity

Journal Article Nottale, Laurent ; Celerier, Marie-Noeelle ; Lehner, Thierry - Journal of Mathematical Physics

Gauge field theory is developed in the framework of scale relativity. In this theory, space-time is described as a nondifferentiable continuum, which implies it is fractal, i.e., explicitly dependent on internal scale variables. Owing to the principle of relativity that has been extended to scales, these scale variables can themselves become functions of the space-time coordinates. Therefore, a coupling is expected between displacements in the fractal space-time and the transformations of these scale variables. In previous works, an Abelian gauge theory (electromagnetism) has been derived as a consequence of this coupling for global dilations and/or contractions. We consider here moremore »« less

Gauge invariance and mass. II. Non-Abelian case

Journal Article Burnel, A - Phys. Rev. D; (United States)

A gauge-invariant formulation of massive non-Abelian vector bosons is discussed. It involves nonrenormalizable couplings in an unphysical sector. All the possibilities of decoupling this unphysical sector are discussed. They include the unitary gauge which is nonrenormalizable, due to propagator difficulties, and all the possible (Lagrangian and non-Lagrangian) non-Abelian generalizations of the Stueckelberg formalism which allow a continuous massless limit. None of them corresponds to a true gauge. On the basis of this presentation, there clearly exists no formulation of massive non-Abelian vector bosons renormalizable by power counting. It is however possible to find gauges where all the difficulties with renormalizabilitymore »« less

Electromagnetic couplings of elementary vector particles

Journal Article Napsuciale, M ; Departamento de Fisica Teorica and Instituto de Fisica Corpuscular, Centro Mixto Universidad de Valencia-CSIC, 46000 Burjassot, Valencia ; Rodriguez, S ; ... - Physical Review. D, Particles Fields

On the basis of the three fundamental principles of (i) Poincare symmetry of space-time, (ii) electromagnetic gauge symmetry, and (iii) unitarity, we construct an universal Lagrangian for the electromagnetic interactions of elementary vector particles, i.e., massive spin-1 particles transforming in the ((1/2),(1/2)) representation space of the homogeneous Lorentz group. We make the point that the first two symmetries alone do not fix the electromagnetic couplings uniquely but solely prescribe a general Lagrangian depending on two free parameters, here denoted by {xi} and g. The first one defines the electric-dipole and the magnetic-quadrupole moments of the vector particle, while the secondmore »« less

Poincare gauge theory of gravity: Friedman cosmology with even and odd parity modes: Analytic part

Journal Article Baekler, Peter ; Hehl, Friedrich W ; Nester, James M ; ... - Physical Review. D, Particles Fields

We propose a cosmological model in the framework of the Poincare gauge theory of gravity (PG). The gravitational Lagrangian is quadratic in both curvature and torsion. In our specific model, the Lagrangian contains (i) the curvature scalar R and the curvature pseudoscalar X linearly and quadratically (including an RX term) and (ii) pieces quadratic in the torsion vector V and the torsion axial vector A (including a VA term). We show generally that in quadratic PG models we have nearly the same number of parity conserving terms ('world') and of parity violating terms ('shadow world'). This offers new perspectives inmore »« less
