چکیده

Nonabelian electrodynamics is a formalism electrodynamics with a cyclicity condition that predicts the existence of a magnetic field called B[1]. This magnetic field has been upheld as a reason for Inverse Faraday effects. Nonabelian electrodynamics, often called O(3) electrodynamics, requires that electroweak unification, based on Glashow, Salam, and Weinberg, be modified to include this extension of electrodynamics to a symmetry that is larger than the U(1) gauge theory. It was recently suggested by Erler and Langacker [2] that an anomaly in Z decay widths points to the existence of Z’ bosons. These are predicted to exist with a mass estimate of 812 GeV–152 within the SO(10) GUT model and a Higgs mass posited at 145 GeV–61. This suggests that a massive neutral boson predicted by Grand Unified Theories has been detected. Further, variants of string theories predict the existence of a large number of these neutral massive bosons. Analyses of the hadronic peak cross section data obtained at LEP 1[2] implies a small amount of missing invisible width in Z decays. These data imply an effective number of massless neutrinos, N = 2.985 0.008, which is below the prediction of 3 standard neutrinos by the standard model of electroweak interactions. The weak charge QW in atomic parity violation can be interpreted as a measurement of the S parameter. This indicates a new QW = –72.06 0.44 is found to be above the standard model prediction. This effect is interpreted as due to the occurrence of the Z’ particle, which will be referred to as the Z particle. SO(10) has the six roots i i = 1 6. The angle between the connected roots are all 120, where the roots 3 4 are connected to each other and two other roots. The Dynkin diagram is illustrated below:

HIGGS-STRAHLUNG AND WW FUSION IN ee COLLISIONS

Higgs-strahlung ee → ZH and WW fusion ee → ν̄eνeH are the most important mechanisms for the production of Higgs bosons in ee collisions at LEP2 and future ee linear colliders. We have calculated the cross sections and energy/angular distributions of the Higgs boson for these production mechanisms. When the Z boson decays into (electron-)neutrinos, the two production amplitudes interfere. In the ...

Resolving the AbFB puzzle in an extra dimensional model with an extended gauge structure

It is notorious that, contrary to all other precision electroweak data, the forward– backward asymmetry for b quarks AFB measured in Z decays at LEP1 is nearly three standard deviations away from the predicted value in the Standard Model; significant deviations also occur in measurements of the asymmetry off the Z pole. We show that these discrepancies can be resolved in a variant of the Randal...

Electroweak Symmetry Breaking at the Supercollider

As we have heard throughout this conference, the standard model of particle physics is in excellent agreement with experiment. Precision measurements have confirmed that the strong, weak and electromagnetic forces are described by a nonabelian gauge theory based on the group SU(3) × SU(2) × U(1). This is a remarkable achievement, one for which particle physicists have every right to feel proud....

Supersymmetry and Finite Radiative Electroweak Breaking from an Extra Dimension ∗

A five dimensional N = 1 supersymmetric theory compactified on the orbifold S 1 /Z 2 is constructed. Gauge fields and SU (2) L singlets propagate in the bulk (U-states) while SU (2) L doublets are localized at an orbifold fixed point brane (T-states). Zero bulk modes and localized states constitute the MSSM and massive modes are arranged into N = 2 supermultiplets. Superpotential interactions o...

Electroweak Theory and the 1996/97 Precision Electroweak Data * †

We review the empirical evidence for the validity of the Standard Electroweak Theory in Nature. The experimental data are interpreted in terms of an effective Lagrangian for Z physics, allowing for potential sources of SU(2) violation and containing the predictions of the Standard Electroweak Theory as a special case. Particular emphasis is put on discriminating loop corrections due to fermion-...
