# Flavon VEV Scales in U(3)$\times$U(3)$'$ Model

@article{Koide2017FlavonVS, title={Flavon VEV Scales in U(3)\$\times\$U(3)\$'\$ Model}, author={Yoshio Koide and Hiroyuki Nishiura}, journal={International Journal of Modern Physics}, year={2017}, pages={1750085} }

We have recently proposed a quark and lepton mass matrix model based on U(3)×U(3)′ family symmetry as the so-called Yukawaon model, in which the U(3) symmetry is broken by VEVs of flavons (Φf)iα which are (3,3∗) of U(3)×U(3)′. The model has successfully provided the unified description of quark and lepton masses and mixings by using the observed charged lepton masses as only family-number dependent input parameters. However, our final goal is not only to give well-satisfied fitting of quark and…
