Abstract
Mass matrices are discussed in the standard model, taking into account the small observed value of CP violation, in order to disclose possible patterns. A particular mass pattern emerges in the limit of small CP violation. We obtain the following relations between the Kobayashi-Maskawa matrix elements and the quark masses: |Vub|≃ms2mb2|Vus||Vcb| and |Vtd|≃|Vus||Vcb|(ms2mb2+|Vcb|2), which imply that the measure of CP violation is approximated by |J|≃ms2mb2|Vus|2.Keywords
