Title: Electroweak symmetry breaking in TeV-scale string models

Abstract

We propose a scenario of the electroweak symmetry breaking by one-loop radiative corrections in a class of string models with D3-branes at non-supersymmetric orbifold singularities with the string scale in TeV region. As a test example, we consider a simple model based on a D3-brane at locally C3/Z6 orbifold singularity, and the electroweak Higgs doublet fs are identified with the massless bosonic modes of the open string on that D3-brane. They have Yukawa couplings with three generations of left-handed quarks and right-handed up-type quarks which are identified with the massless fermionic modes of the open string on the D3-brane. We calculate the one-loop correction to the Higgs mass due to the non-supersymmetric string spectrum and interactions, and qualitatively suggest that the negative mass squared can be generated. The problems which must be solved to proceed quantitative calculations are pointed out.

  • In a recent paper, we proposed a new class of supersymmetric SO(10) models for neutrino masses where the TeV-scale electroweak symmetry is SU(2){sub L}xSU(2){sub R}xU(1){sub B-L}, making the associated gauge bosons W{sub R} and Z{sup '} accessible at the Large Hadron Collider. We showed that there exists a domain of Yukawa coupling parameters and symmetry breaking patterns which give an excellent fit to all fermion masses including neutrinos. In this sequel, we discuss an alternative Yukawa pattern which also gives a good fermion mass fit, and then study the predictions of both models for the proton lifetime. Consistency with currentmore » experimental lower limits on the proton lifetime require the squark masses of the first two generations to be larger than {approx}1.2 TeV. We also discuss how one can have simultaneous breaking of both SU(2){sub R}xU(1){sub B-L} and standard electroweak symmetries via radiative corrections.« less
  • The authors discuss symmetry breaking and phenomenological aspects of rank 6 effective models in 4 dimensions, suggested by Calabi-Yau compactification of the heterotic E/sub 8/ x E/sub 8/ superstring, which have gauge group SU(3)/sub C/ x SU(2)/sub L/ x SU(2) x U(1)'. The simplest and most natural form of electroweak symmetry breaking for the softly broken effective SUSY theory is considered, and only those additions and alterations to the 27/sup 3/ based superpotential necessary to eliminate phenomenological problems are made. There are two physically distinct additional SU(2) factors, SU(2)/sub N/ and SU(2)/sub R/. The former has all gauge bosons electricallymore » neutral, the latter both charged and neutral. The additional SU(2) symmetry implies that large Dirac neutrino masses must be eliminated by a see-saw mechanism requiring the introduction of an E/sub 6/ singlet per generation and an intermediate scale of symmetry breaking M/sub I/(/ge/10/sup 10/ GeV). The intermediate scale symmetry breaking together with the couplings involving E/sub 6/ singlets needed for the see-saw mechanism unambiguously determines the form of the superpotential describing physics at low scales /approx/ 1 TeV. All additional heavy charge -1/3 quarks and additional Higgs doublets have masses /approx/ 1 TeV. An additional U(1)/sub E/ remains unbroken down to the 1 TeV scale. The resulting effective theories have no U(1)/sub E/ mediated FCNC due to mixing of heavy and light charge -1/3 quarks. Some couplings must be eliminated in order to prevent rapid nucleon decay.« less
  • One of the puzzles of the standard model is why the mass parameter {mu}{sup 2} , which determines the weak interaction scale, is closer to the quantum chromodynamics scale than to the grand unification or Planck scales. We consider a novel approach to this problem, based upon the idea that {mu}{sup 2} takes different values in different domains of the Universe. The whole range of values for {mu}{sup 2} , from +M{sup 2}{sub P} to {minus}M{sup 2}{sub P} , is explored, and it is found that only for values in a narrow window is life likely to be possible. Themore » observed value of {mu}{sup 2} is fairly typical of the values in this window. {copyright} {ital 1998} {ital The American Physical Society}« less
  • We present a top-condensation model in which the CP symmetry is spontaneously broken at the electroweak scale due to the condensation of two composite Higgs doublets. In particular the CP-violating phase of the Cabibbo-Kobayashi-Maskawa quark-mixing matrix is generated. A simpler model where only one quark family is included is also discussed. In this case, for a general four-fermion interaction (G{sub tb}{ne}0), the particle spectrum is the one of the one Higgs doublet model.
  • Through a detailed numerical investigation in three spatial dimensions, we demonstrate that long-lived time-dependent field configurations emerge dynamically during symmetry breaking in an expanding de Sitter spacetime. We investigate two situations: a single scalar field with a double-well potential and an SU(2) non-Abelian Higgs model. For the single scalar, we show that large-amplitude oscillon configurations emerge spontaneously and persist to contribute about 1.2% of the energy density of the Universe. We also show that for a range of parameters, oscillon lifetimes are enhanced by the expansion and that this effect is a result of parametric resonance. For the SU(2) case,more » we see about 4% of the final energy density in oscillons.« less
