Charged Lepton Mass Relations in a Supersymmetric Yukawaon Model
Abstract
According to an idea that effective Yukawa coupling constants Yfeff are given vacuum expectation values < Yf> of fields ("Yukawaons") Yf as Yfeff=yf < Yf>/, a possible superpotential form in the charged lepton sector under a U(3) [or O(3)] flavor symmetry is investigated. It is found that a specific form of the superpotential can lead to an empirical charged lepton mass relation without any adjustable parameters.
