Weak and electromagnetic interactions of the leptons are examined under the hypothesis that the weak interactions are mediated by vector bosons. With only an isotopic triplet of leptons coupled to a triplet of vector bosons (two charged decay-intermediaries and the photon) the theory possesses no partial-symmetries. Such symmetries may be established if additional vector bosons or additional leptons are introduced. Since the latter possibility yields a theory disagreeing with experiment, the… Expand
Model of Weak - and Electromagnetic - Interaction Symmetry
A model that unites the intermediate boson of the weak interaction and the photon of the electromagnetic interaction into a multiplet of gauge fields is considered. Weak leptonic currents andExpand

Weak and electromagnetic interaction symmetry
An analogy between a triplet of quarks and a triplet of leptons is discussed in the framework of a model of weak and electromagnetic interactions possessing local SU(2)L × U(1) symmetry. After theExpand

At the core of our present understanding of weak interactions is the mediation of the weak force between two point-like fermions via a weak intermediate vector boson, W+- or Z0 with vector and axialExpand

Abstract We study the possibility to detect heavy physics effects in the interactions of Higgs bosons and the top quark at future colliders using the effective Lagrangian approach, where the SMExpand
Bounds on the number and masses of quarks and leptons
Abstract We assume weak, electromagnetic and strong interactions to be asymptotically divergent, and to become strong at very large energies, of the order of the Plank mass. In this picture, theExpand
Composite Quarks and Leptons
The present theory of particle physics is the standard model of strong and electroweak interactions [1]. It is a renormalizable quantum field theory which describes sucessfully all our experimentalExpand
