Baryon asymmetry of the Universe in the minimal standard model.
We calculate the baryon asymmetry of the Universe which would arise during a first order electroweak phase transition due to minimal standard model processes. It agrees in sign and magnitude with the observed baryonic excess, for resonable KM parameters and mt in the expected range, and plausible values of bubble velocity and other high temperature effects.

متن کاملNote Added to “ Baryon Asymmetry of the Universe in the Standard Model ” 1
Recent papers by Gavela et al and Huet et al claim to have shown that incluion of higher order interactions between quasiparticles dramatically decreases the baryon asymmetry of the universe which can arise in the Minimal Standard Model. These papers employ an inconsistent calculational scheme which, for instance, violates unitarity. We argue that their method cannot be considered as reliable, ...
متن کاملThe Baryon Asymmetry of the Universe
The possibility to explain the CMB measurement of the baryon asymmetry with leptogenesis results in a stringent bound on neutrino masses such that √ m1 + m 2 2 + m 2 3 < 0.30eV. We discuss the implications of such a bound for future experiments on the absolute neutrino mass scale. 1. THE BARYON ASYMMETRY OF THE UNIVERSE The observation of the acoustic peaks in the power spectrum of CMB temperat...
متن کاملStandard Model CP - violation and Baryon asymmetry
Simply based on CP arguments, we argue against a Standard Model explanation of the baryon asymmetry of the universe in the presence of a first order phase transition. A CP-asymmetry is found in the reflection coefficients of quarks hitting the phase boundary created during the elec-troweak transition. The problem is analyzed both in an academic zero temperature case and in the realistic finite ...
متن کاملBaryon Asymmetry of Universe : View from Superfluid
The origin of the excess of matter over antimatter in our Universe remains one of the fundamental problems. The dynamical baryogenesis in the process of the broken symmetry electroweak transition in the expanding Universe is the widely discussed model where the baryonic asymmetry is induced by the quantum chiral anomaly. We discuss the modelling of this phenomenon in superfluid He and supercond...
