Title:SU(2) Yang-Mills thermodynamics and its implications for the cosmological model
Abstract:Based on a non-perturbative and largely analytical approach to Yang-Mills thermodynamics and considering the low-frequency excess of radiance in the present CMB spectrum we put forward the postulate that thermal photon gases are subject to an SU(2) rather than a U(1) gauge principle. Implications for the CMB temperatureredshift relation and the dark sector of the cosmological model are discussed. In this context, the local-global H0 discrepancy is reduced to the common use of a U(1) model for CMB photons in parameter fits to the extremely well measured CMB power spectra.
