Abstract
The fine-tuning principles are examined to predict the top-quark and H iggs-boson masses. The modification of the Veltman condition based on the compensation of vacuum energies is developed. It is implemented in the Standard Model and in its minimal extension with two Higgs double ts. The top-quark and Higgs-boson couplings are fitted in the SM for t he lowest ultraviolet scale where the fine-tuning can be stable under resealing. It yields the low-energy values m(t) similar or equal to 17 5 GeV, m(H) similar or equal to 210 GeV.
