On the neutrino and electron masses in the theory of scale relativity

TL;DR

This paper proposes a theoretical relation linking neutrino and electron masses to the Planck mass using scale relativity, predicting specific neutrino masses consistent with experimental data.

Contribution

It introduces a new relation for neutrino masses based on scale relativity, extending previous electron mass relations, and provides specific mass predictions.

Findings

Predicted lightest neutrino mass: 0.0214 eV

Heavier neutrino masses: 0.0231 eV and 0.0552 eV

Relation aligns with neutrino oscillation data

Abstract

We have long ago derived a theoretical relation between the mass of the electron and the fine structure constant \cite{Nottale1994}, which writes to lowest order $\alpha \ln (m_{\mathbb{P}}/m_e) = 3/8$ (where $m_{\mathbb{P}}$ is the Planck mass). We suggest the existence of a similar relation valid for neutrinos, $\alpha \ln ({m_{\mathbb{P}}}/{m_\nu} ) =1/2$. From this relation, we theoretically predict a lightest neutrino mass $m_{\nu} = m_{\mathbb{P}}\exp (-\alpha^{-1}/2 )=0.0214$ eV. The masses of the two heavier neutrinos, $0.0231$ eV and $0.0552$ eV, can then be obtained from experimental results of neutrino oscillations.
