    • Abstract

       

      Fritzsch like mass matrices with non-zero 22-elements both in U sector and D sector have been investigated in the context of latest data regardingmtphys, |Vub|, |Vcb|, |Vtd| and |Vts|. Unlike several other phenomenological models, the present model not only accommodates the value ofmtphys in the range 150–240 GeV, encompassing the CDF and D0 values, but is also able to reproduce |Vcb| ≊0.040 and |Vub/Vcb| = 0.08±0.02 and |Vtd| is predicted to lie in the range 0.005–0.014. Further, the angles of the unitarity triangle, related to the CP-violating asymmetries, are calculated to be in the ranges −1.0⩽sin2α⩽−0.1, 0.6 ⩽sin2α⩽1.0 and 0.48⩽sin2β⩽0.56, which are in agreement with other recent calculations.
