Abstract: (WSP)
I modify the calculation of the QCD correction factors in the ΔS = 2 effective Lagrangian for K0K0K^0 -\overline K^0 mixing to allow top quark masses in the range 50 GeV to 200 GeV. I give constraints on the top mass and Kobayashi-Maskawa phase, determined from the measured K0K0K^0 -\overline K^0 mixing parameter ε, and find that the factor BK and the ratio |Vub/Vcb| cannot both be smalI if mt < 200 GeV.
