Getting at the Quark Mass Matrices
Abstract
We present a class of Ansatze for the up and down quark mass matrices which leads approximately to: |Vus| md / ms, |Vcb| ms / mb, and |Vub / Vcb| mu / mc. Sizes of the Kobayashi-Maskawa matrix elements are controlled solely by quark mass ratios. In particular, we introduce no other small parameter and our results do not rely on delicate cancellation.
