Possible Effects of a Composite Iso-Scalar Weak Boson in a Left-Right Symmetric Preon Model

Abstract

We assume that a fundamental gauge symmetry is never brokenj, and any short range interactions should be secondary, appearing as residual effects of some fundamental gauge interactions. On this assumption the weak interaction is considered to be a secondary effective one among composite quarks, leptons and weak bosons with respective appropriate preon and/or anti-Preon configurations bounded by a new fundamental gauge interaction. In this work, applying a fermion-boson type preon scheme and supposing confinement and a preon line rule (like the OZI-rule) for the confining force, we concentrate to investigate lower mass limit of the additional iso-scalar particle, whose existence in naturally expected in our scheme, permitted by a low energy experiment
