Third Family Corrections to Quark and Lepton Mixing in SUSY Models with non-Abelian Family Symmetry

Understand

We re-analyse the effect of corrections from canonical normalisation of kinetic terms on the quark and lepton mixing angles.

• This type of corrections emerges, for example, from effective higher-dimensional Kahler potential operators in the context of locally supersymmetric models of flavour.
• In contrast to previous studies we find that the necessary procedure of redefining the fields in order to restore canonically normalised kinetic terms, i.e.
• canonical normalisation, can lead to significant corrections to the fermion mixing angles (as determined from the superpotential).
