A Modest Revision of the Standard Model

TL;DR

This paper proposes a modest revision to the Standard Model's mass sector, enhancing understanding of fermion masses, mixings, and implications for physics beyond the Standard Model, including insights into neutrino oscillations.

Contribution

It introduces a revised framework for fermion masses and mixings that links them to beyond Standard Model physics and reduces the Higgs Yukawa coupling constant significantly.

Findings

Systematics of fermion masses and mixings explained

Reduction of Higgs Yukawa coupling by an order of magnitude

Enhanced understanding of quark and lepton mixing differences

Abstract

With a modest revision of the mass sector of the Standard Model, the systematics of the fermion masses and mixings can be fully described and interpreted as providing information on matrix elements of physics beyond the Standard Model. A by-product is a reduction of the largest Higgs Yukawa fine structure constant by an order of magnitude. The extension to leptons provides for insight on the difference between quark mixing and lepton mixing as evidenced in neutrino oscillations. The large difference between the scale for up-quark and down-quark masses is not addressed. In this approach, improved detail and accuracy of the elements of the current mixing matrices can extend our knowledge and understanding of physics beyond the Standard Model.
