TL;DR
This paper proposes a novel mechanism for generating naturally light Dirac neutrino masses using composite Higgs and new physics beyond the standard model, linking neutrino mass to new physics at accessible energy scales.
Contribution
It introduces a new mechanism involving composite Higgs and beyond standard model interactions to explain neutrino masses.
Findings
Neutrino mass of 0.1 eV or higher implies new physics at 10-100 TeV.
The mechanism naturally produces light Dirac neutrinos.
Connects neutrino mass scale to accessible energy ranges.
Abstract
A mechanism for generating massive but naturally light Dirac neutrinos is proposed. It involves composite Higgs within the standard model as well as some new interaction beyond the standard model. According to this scenario, a neutrino mass of 0.1 eV or higher, signals new physics at energies of 10--100 TeV or lower.
