Family symmetries and alignment in multi-Higgs doublet models
arXiv:1104.2601 · doi:10.1016/j.physletb.2011.06.042
Abstract
The exact alignment of the Yukawa structures on multi-Higgs doublet models provides cancellation of tree-level flavour changing couplings of neutral scalar fields. We show that family symmetries can provide a suitable justification for the Yukawa alignment.
