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

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.
