Charged Lepton Mass Relations in a Supersymmetric Yukawaon Model

Understand

According to an idea that effective Yukawa coupling constants Y_f^{eff} are given vacuum expectation values < Y_f> of fields (&#34;Yukawaons&#34;) Y_f as Y_f^{eff}=y_f < Y_f>/\Lambda, 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.
