Abstract Authors Article Text Introduction. Baryogenesis from SM baryon number Axion-induced C P violation and Axion dark matter. Higgs quench from a Higgs-scalar Naturally delayed EW phase transition Conclusion. ACKNOWLEDGMENTS References
We show that strong C P violation from the QCD axion can be responsible for the matter antimatter cool maths games asymmetry cool maths games of the Universe in the context of cold electroweak baryogenesis if the electroweak phase transition is delayed below the GeV scale. This can occur naturally if the Higgs couples to a O ( 100 ) GeV dilaton, as expected in some models where the Higgs is a pseudo-Nambu-Goldstone boson of a new strongly interacting sector at the TeV scale. The existence of such a second scalar resonance with a mass and properties similar to the Higgs boson will soon be tested at the LHC. In this context, the QCD axion would not only solve the strong cool maths games C P problem, but also the matter antimatter asymmetry and dark matter.

Today s baryon asymmetry as a function of TEWPT compared with measured value (dotted line). The case Teff/Treh=1 and Teff TEWPT that would characterize standard EW baryogenesis is unfeasible as Treh O(mH) ΛQCD. The cases with Teff/Treh 10 can easily account for a large B asymmetry and correspond to a quenched EWPT, as in cold EW baryogenesis. Each band corresponds to varying the initial angle Θ i in the range [10-2,π/2]. Left: ma 3HEW 3 10-14 GeV, oscillations start at T=0.3 GeV in the supercooling era before the EWPT. Right: ma 3HEW, the axion is frozen to its initial value until after reheating. cool maths games Reuse & Permissions ×
