What Physics Does The Charged Lepton Mass Relation Tell Us?

Abstract

The charged lepton mass relation $K\equiv (m_e+m_{\mu }+m_{\tau })/(\sqrt{m_e}$ is excellently satisfied by observed masses (pole masses). However, the formula $K=2/3$ should be never satisfied with the observed charged lepton masses. We will review a mechanism by proposed by Sumino and recent related topics.
