A Model Behind the Standard Model

This closer study of the FSM: [I] retains the earlier results in offering explanation for the existence of three fermion generations, as well as the hierarchical mass and mixing patterns of leptons and quarks; [II] predicts a vector boson $G$ with mass of order TeV which mixes with $\gamma$ and $Z$ of the standard model. The subsequent deviations from the standard mixing scheme are calculable in terms of the $G$ mass. While these deviations for (i) $m_Z - m_W$, (ii) $\Gamma(Z...

We show that the local conformal group $C$ is a natural symmetry group of strong, electroweak and gravitational interactions. A model for these interactions invariant under the local symmetry group $G=SU(3)\times SU(2)_{L}\times U(1)\times C$ is postulated. It contains all Standard Model and gravitational fields, however the Higgs mass term $\mu^2\Phi^{\dagger}\Phi$ is forbidden. Using the unitary gauge and the conformal scale fixing conditions we can eliminate all four real ...

A model for strong, electroweak and gravitational interactions based on the local symmetry group $G=SU(3)\times SU(2)_{L}\times U(1)\times C$ where $C$ is the local conformal symmetry group is proposed. The natural minimal $G$-invariant form of total lagrangian is postulated. It contains all Standard Model fields and the gravitational interaction, however the Higgs mass term $\mu^2\Phi^{\dagger}\Phi$ is forbidden. Using the unitary gauge and the conformal scale fixing conditi...

We propose a fundamental theory whose low-energy effective theory provides a phenomenological description of electroweak baryogenesis, radiative neutrino mass generation, and dark matter. The model is based on SUSY SU(2)_H gauge theory with confinement, and the model contains new Z_2 discrete symmetry and Z_2-odd right-handed neutrino superfields. The Higgs sector in the low energy effective theory of this model below confinement scale is described by fifteen mesonic superfie...

We declare that we live in the quantum 4-dimensional Minkowski space-time with, via the gauge principle, the force-fields gauge-group structure, $SU_c(3) \times SU_L(2) \times U(1)$ applied to the quark world or $SU_L(2) \times U(1) \times SU_f(3)$ applied to the lepton world, built-in from the very beginning. The quark world with the triplets from the "quark" group $SU_Q(3)$ (used to be called "flavor $SU(3)$ symmetry"), which is of nuclear sizes and is protected by $SU_c(3)...

A dynamical mechanism of symmetry breaking in which gauge and matter fields play an active role is proposed. It basically represents a covariant generalization of the mechanism responsible for superconductivity, and provides a {\em natural} mechanism of generation of mass which is not in conflict with the present value of the cosmological constant. When applied to SU(2)$\times$U(1) leads to exactly the same physics (Lagrangian density) as the Standard Model but modifying {\em...

If the gauge fields of the Standard Model propagate in TeV-size extra dimensions, they rapidly become strongly coupled and can form scalar bound states of quarks and leptons. If the quarks and leptons of the third generation propagate in 6 or 8 dimensions, we argue that the most tightly bound scalar is a composite of top quarks, having the quantum numbers of the Higgs doublet and a large coupling to the top quark. In the case where the gauge bosons propagate in a bulk of a ce...

A mechanism is suggested by which the dynamics of confinement could be responsible for the fermion mass matrix. In this approach the large top quark Yukawa coupling is generated naturally during confinement, while those of the other quarks and leptons stem from non-renormalizable couplings at the Planck scale and are suppressed. Below the confinement scale(s) the effective theory is minimal supersymmetric $SU(5)$ or the supersymmetric standard model. Particles in the $\bar 5$...

With SU(3) gauge Higgs theory as an example, we examine critically the idea that the confinement property in an SU(N) gauge-Higgs theory, with the Higgs field in the fundamental representation, persists in an unbroken SU(N-1) subgroup.
