Supersymmetry and the quark mass matrix

Research output: Contribution to journalArticle

We describe a class of supersymmetric models which make qualitative predictions for the structure of the quark mass matrix. In particular the models explain the large ratios between the masses of third generation particles and those of the two lighter generations, as well as the smallness of third generation mixing angles. They can also explain why grand unified predictions for quark lepton mass ratios might work only for the third generation. A natural mechanism for explaining why charge 2 3 quarks are generally heavier than those with charge -1 3 is also found.
