With the parameters, i.e., the Higgs VEVs already fitted in a very successful way to quark and lepton masses and mixing angles we obtain the order of magnitude pure prediction Y_B=2.59{+17.0\atop-2.25}\times 10^{-11} which according to a theoretical estimate should mean in this case an uncertainty of the order of a factor 7 up or down (to be compared to Y_B=(1.7-8.1)\times 10^{-11}) using a relatively crude approximation for the dilution factor, while using another estimate based on Buchmüller and Plümacher a factor 500 less, but this should rather be considered a lower limit. With a realistic uncertainty due to wash-out of a factor 100 up or down we even with the low estimate only deviate by 1.5σ.8 pages, no figure, LaTeX2e, Talk given at 8th Adriatic Meeting and Central European Symposia on Particle Physics in the New Millennium, 4-14 Sep. 2001, Dubrovnik, CroatiaHigh Energy Physics - Phenomenologytext
