Connes' interpretation of the Standard Model and massive neutrinos

TL;DR

This paper explores how noncommutative geometry can incorporate massive neutrinos into the Standard Model, leading to a revised Higgs mass prediction.

Contribution

It provides a new computation of the Standard Model Lagrangian with nonzero neutrino masses within a noncommutative geometric framework.

Findings

Revised Higgs mass prediction higher than in massless neutrino models

Successful integration of massive neutrinos into noncommutative geometry approach

Enhanced understanding of neutrino mass effects on Standard Model parameters

Abstract

Massive neutrinos can be accommodated into the noncommutative geometry reinterpretation of the Standard Model. The constrained Standard Model Lagrangian is computed anew under the assumption of nonzero neutrino masses. This gives the ``prediction" of a mass for the Higgs particle somewhat higher than in the vanishing neutrino mass case.
