• Lower bound ofmt from$$B_d^0 - \bar B_d^0$$ mixing and recent |Vub|/|Vcb| measurementsmixing and recent |Vub|/|Vcb| measurements

A careful analysis of$$B_d^0 - \bar B_d^0$$ mixing data, incorporating the most recent QCD corrections to the parameterxd, as well as the recent data regarding the matrix elements |Vub| and |Vcb| leads to a reliable lower limit on mass oft-quark, for examplemt ⩾ 115 GeV.

• Fermilab top mass and modified Fritzsch mass matrices

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.
