Weinberg Angle, Neutron Abundance in BBN, and Lifetime
Cheng Tao Yang, Johann Rafelski
We present state of the art kinetic theory determination of the neutron abundance available for the Big-Bang nucleosynthesis (BBN). Our work is motivated by the study of the neutro…
Higgs Thermal Nonequilibrium in Primordial QGP
Cheng Tao Yang, Shelbi Foster, Johann Rafelski
In this work we investigate the chemical and kinetic nonequilibrium dynamics of the Higgs boson during the primordial Universe QGP (quark-gluon plasma) epoch $130\mathrm{\,GeV}>T>1…
Higgs in The Cosmos
Johann Rafelski, Cheng Tao Yang
We explore the Higgs particle in the cosmic quark-gluon plasma (QGP) below the electroweak phase transition temperature . We show that Higgs…
Self-consistent strong screening applied to thermonuclear reactions
Christopher Grayson, Cheng Tao Yang, Martin Formanek +1
Self-consistent strong plasma screening around light nuclei is implemented in the Big Bang nucleosynthesis (BBN) epoch to determine the short-range screening potential, $eÏ(r)/T \…
Fermi-Dirac Integrals in Degenerate Regimes: A Novel Asymptotic Expansion
Jeremiah Birrell, Martin Formanek, Andrew Steinmetz +2
We characterize in a novel manner the physical properties of the low temperature Fermi gas in the degenerate domain as a function of temperature and chemical potential. For the fir…
