摘要

In the so-called yukawaon model, where the eective Yukawa coupling constants Y e f (f = e; ; u; d) are given by vacuum expectation values (VEV's) of gauge singlet scalars (yukawaons) Yf with 33 components, i.e. Y e f = yf hYf i=, massless (and light) scalars appear because a global avor symmetry is assumed. In order to demonstrate whether such massless scalars in the yukawaon model are harmless or not, yukawaon masses are explicitly estimated, as an example, in the charged lepton sector.
