U(3)-Flavor Nonet Scalar as an Origin of the Flavor Mass Spectra
Abstract
Description
According to an idea that the quark and lepton mass spectra originate in a VEV structure of a U(3)-flavor nonet scalar Φ, the mass spectra of the down-quarks and charged leptons are investigated. The U(3) flavor symmetry is spontaneously and completely broken by non-zero and non-degenerated VEVs of $Φ$, without passing any subgroup of U(3). The ratios (m_e+m_μ+m_τ)/(\sqrt{m_e}+\sqrt{m_μ}+\sqrt{m_τ})^2 and \sqrt{m_e m_μm_τ}/(\sqrt{m_e}+\sqrt{m_μ}+\sqrt{m_τ})^3 are investigated based on a toy model.
