摘要：We present quantitative and qualitative arguments in favor of the claim that, within the present
cosmological epoch, the U(1)Y factor in the Standard Model is an effective manifestation of SU(2)
pure gauge dynamics of Yang-Mills scale L 104 eV. Results for the pressure and the energy
density in the deconfining phase of this theory, obtained in a nonperturbative and analytical way,
support this connection in view of large-angle features inherent in the map of the CMB temperature
fluctuations and temperature-polarization cross correlations.
