Weak-Boson Mass from Available Neutrino Data

Neutrino Masses and the Structure of the Weak Gauge Boson

A composite model of fermions is used to estimate neutrino masses. The formula for masses in the model is approximate and neglects the small masses of the electrically neutral systems (neutrino). However, in this model the electron-neutrino forms part of the structures of the weak gauge bosons (Wand Z) and, if the masses of these particles are calculated formally using the zero neutrino mass, t...

Neutrino and scalar boson mass in algebraic quantum field theory

The hypothesis is explored that fermion rest mass is due entirely to self-interaction via virtual excitation of gauge bosons. This requires revising the standard model to treat both chiral projections of a fermion field as SU(2) doublets, which precludes Yukawa coupling to a scalar (Higgs) boson field. The estimated self-interaction mass of the electron neutrino is 0.291× 10−5me. The implied se...

Higgs boson mass constraints from precision data and direct searches

Two of the nine measurements of sin2θ eff , the effective weak interaction mixing angle, are found to be in significant conflict with the direct search limits for the Standard Model (SM) Higgs boson. Using a scale factor method, analogous to one used by the Particle Data Group, we assess the possible effect of these discrepancies on the SM fit of the Higgs boson mass. The scale factor fits incr...

The Higgs Boson Mass from Precision Electroweak Data

We present a new global fit to precision electroweak data, including new lowand high-energy data and analyzing the radiative corrections arising from the minimal symmetry breaking sectors of the Standard Model (SM) and its supersymmetric extension (MSSM). It is shown that present data favor a Higgs mass of O(MZ): MH = 76 +152 − 50 GeV We confront our analysis with (meta)stability and perturbati...
