Abstract

We determine the upper bound on the Higgs boson mass from the condition that baryon asymmetry produced during the electroweak phase transition should not be diluted by the anomalous electroweak baryon number non-conserving processes. The value is insensitive to the mass of t-quark and equal to 45 GeV, slightly depending on the magnitute of the preexponential factor in the rate of the B non-conservation. This gives also upper bound on the top quark mass m_t<80 GeV .
