Fritzsch-Xing mass matrices, V{sub td}, and the CP-violating phase {delta}
- Department of Physics, Panjab University, Chandigarh-16001 (India)
Natural four zeros texture mass matrices recently proposed by Fritzsch and Xing are investigated by including {open_quotes}nonleading{close_quotes} corrections in the context of the latest data regarding m{sub t}{sup pole} and V{sub CKM} matrix elements. Apart from accommodating m{sub t}{sup pole} in the range 175{plus_minus}15GeV, {vert_bar}V{sub cb}{vert_bar} and {vert_bar}V{sub ub}/V{sub cb}{vert_bar}=0.08{plus_minus}0.02, the analysis with maximal CP violation predicts {vert_bar}V{sub td}{vert_bar}=0.005{endash}0.013. Further, the CP-violating phase angle {delta} can be restricted to the ranges (i) 22{degree}{endash}45{degree} and (ii) 95{degree}{endash}130{degree}, concretizing the ambiguity regarding the phase of the CKM matrix. Furthermore, we find that nonleading calculations are important when the {open_quotes}Cabibbo triangle{close_quotes} is to be linked to the unitarity triangle. {copyright} {ital 1997} {ital The American Physical Society}
