Lepton Self-Mass, Higgs Scalar and Heavy Quark Masses

This paper has been presented at the DESY Workshop, October 22-24, 1979. Assuming cancellation of lepton self-mass ultraviolet divergences in the SU(2) x U(1) gauge theory, we predict heavy quark t and Higgs scalar masses. In Eq.(6), the mass sum rule necessary to the vanishing of quadratic divergences is formulated.
