Abstract

In supersymmetric theories, topological defects can have nontrivial behaviors determined purely by whether or not supersymmetry is restored in the defect core. A well-known example of this is that some supersymmetric cosmic strings are automatically superconducting, leading to important cosmological effects and constraints. We investigate the impact of nontrivial kinetic interactions, present in a number of particle physics models of interest in cosmology, on the relationship between supersymmetry and supercurrents on strings. Furthermore, we find that in some cases it is possible for superconductivity to be disrupted by the extra interactions.

Inflation in supersymmetric unified theories

Journal Article Jeannerot, R - Physical Review, D

We construct supersymmetric unified models which automatically lead to a period of inflation. The models all involve a U(1) symmetry which does not belong to the MSSM. We consider three different types of models depending on whether this extra U(1) is the subgroup of a non-Abelian gauge group, is a U(1) factor belonging to the visible sector or is a U(1) factor belonging to the hidden sector. Depending on the structure of the unified theory, on the spontaneous symmetry-breaking pattern and on whether we have global or local supersymmetry, inflation may be driven by the nonvanishing vacuum expectation value ofmore »« less

Topological effects in our brane world from extra dimensions

Journal Article Dvali, G ; Kogan, Ian I ; Shifman, M - Physical Review D

The theories in which our world presents a domain wall (brane) embedded in large extra dimensions predict new types of topological defects. These defects arise due to the fact that the brane on which we live spontaneously breaks isometries of the extra space giving mass to some graviphotons. In many cases the corresponding vacuum manifold has nontrivial homotopies -- this gives rise to topologically stable defects in four dimensions, such as cosmic strings and monopoles that carry gravimagnetic flux. The core structure of these defects is somewhat peculiar. Because of the fact that the translation invariance in the extra direction(s)more »« less

TeV and Superheavy Particles from Supersymmetric Topological Defects, the Extragalactic {ital {gamma}} -ray Background, and the Highest Energy Cosmic Rays

Journal Article Bhattacharjee, P ; Stecker, F W ; Bhattacharjee, P ; ... - Physical Review Letters

Cosmic topological defects in a wide class of supersymmetric theories can simultaneously be sources of Higgs bosons of mass{approximately}supersymmetry breaking scale{approximately}TeV , as well as superheavy gauge bosons of mass{approximately}{eta}{gt}1 TeV , {eta} being the gauge symmetry breaking scale. Decay of these Higgs and gauge bosons may contribute significantly to the extragalactic diffuse {gamma} -ray background (EDGRB) above {approximately}10 GeV and explain the highest energy cosmic ray (HECR) flux above {approximately}10{sup 11} GeV , respectively. Cosmic strings with {eta} much above 10{sup 14} GeV overproduce both HECR and EDGRB, and hence are ruled out, {ital if} massive particle radiation ismore »« less

Fermionic vacuum polarization by a composite topological defect in higher-dimensional space-time

Journal Article Bezerra de Mello, E R ; Saharian, A A ; Department of Physics, Yerevan State University, 1 Alex Manoogian Street, 0025 Yerevan - Physical Review. D, Particles Fields

We investigate the vacuum polarization effects associated with a charged massless spin-1/2 field in a higher-dimensional space-time, induced by a composite topological defect. The defect is constituted by a global monopole living on a three brane and two-dimensional conical space transverse to the latter. In addition, we assume the presence of an extra magnetic flux along the core of the conical space. The heat kernel and the Feynman Green function are presented in the form of a sum of two terms. The first one corresponds to the contribution coming from the bulk with global monopole in the absence of conicalmore »« less

Supersymmetry and gauge invariance constraints in a U(1){times}U(1){prime}-Higgs superconducting cosmic string model

Journal Article Morris, J R - Physical Review, D

A supersymmetric extension of the U(1){times}U(1){prime}-Higgs bosonic superconducting cosmic string model is considered, where the action is constructed from scalar chiral and vector superfields. The chiral superfields are assumed to transform separately under the Abelian gauge groups, and the constraints imposed upon such a model due to renormalizability, supersymmetry, and gauge invariance are examined. For a simple model with a single U(1) chiral superfield and a single U(1){prime} chiral superfield, the Witten mechanism for bosonic superconductivity (giving rise to long-range gauge fields outside of the string) does not exist without the introduction of extra chiral supermultiplets. The simplest model thatmore »« less
