Family Replicated Calculation of Baryogenesis
/ Authors
/ Abstract
In our model with a Standard Model gauge group extended with a baryon number minus lepton number charge for each family of quarks and leptons, we calculate the baryon number relative to entropy produced in early Big Bang by the Fukugita- Yanagida mechanism. 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 -2.25 ×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)×10-11) using a relatively crude approximation for the dilution factor, while using another estimate based on Buchmuller and Plumacher 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.
