On the generality of certain predictions for quark mixing

Abstract

The relations $\frac{|V_{ub}|}{|V_{cb}|}=\sqrt{\frac{m_u}{m_c}}$ and $\frac{|V_{td}|}{|V_{ts}|}=\sqrt{\frac{m_d}{m_s}}$ are significant successes of some specific models for quark masses. We show that these relations are more general, resulting from a much wider class of models. Consequences of these predictions for CP violating asymmetries in neutral B meson decays are discussed.
