Abstract
Baryon-number generation via SU(5) Higgs-boson decay in the early Universe is investigated at finite temperatures. It is shown that the imaginary part of the Higgs-boson decay amplitude is increased at temperatures near the Higgs-boson mass, which causes a slight enhancement of the final baryon-to-entropy ratio of the Universe.Keywords
