Electroweak symmetry breaking in TeVscale string models
Abstract
We propose a scenario of the electroweak symmetry breaking by oneloop radiative corrections in a class of string models with D3branes at nonsupersymmetric orbifold singularities with the string scale in TeV region. As a test example, we consider a simple model based on a D3brane 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 D3brane. They have Yukawa couplings with three generations of lefthanded quarks and righthanded uptype quarks which are identified with the massless fermionic modes of the open string on the D3brane. We calculate the oneloop correction to the Higgs mass due to the nonsupersymmetric 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 TeVscale electroweak symmetry is SU(2){sub L}xSU(2){sub R}xU(1){sub BL}, 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.

Implications of symmetry breaking and phenomenology for superstring based models with gauge symmetry SU(3)/sub C/ x SU(2)/sub L/ x SU(2) x U(1) x SU(2) x U(1) x U(1)'
The authors discuss symmetry breaking and phenomenological aspects of rank 6 effective models in 4 dimensions, suggested by CalabiYau 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 » 
Anthropic Considerations in MultipleDomain Theories and the Scale of Electroweak Symmetry Breaking
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.

Spontaneous CP symmetry breaking at the electroweak scale
We present a topcondensation 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 CPviolating phase of the CabibboKobayashiMaskawa quarkmixing matrix is generated. A simpler model where only one quark family is included is also discussed. In this case, for a general fourfermion interaction (G{sub tb}{ne}0), the particle spectrum is the one of the one Higgs doublet model. 
Longlived timedependent remnants during cosmological symmetry breaking: From inflation to the electroweak scale
Through a detailed numerical investigation in three spatial dimensions, we demonstrate that longlived timedependent field configurations emerge dynamically during symmetry breaking in an expanding de Sitter spacetime. We investigate two situations: a single scalar field with a doublewell potential and an SU(2) nonAbelian Higgs model. For the single scalar, we show that largeamplitude 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 »
