    • Abstract

       

      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.
