The muon abundance in the primordial Universe
Jan Rafelski, Cheng Tao Yang
Muon abundance is required for the understanding of several fundamental questions regarding properties of the primordial Universe. In this paper we evaluate the production and deca…
Possibility of bottom-catalyzed matter genesis near to primordial QGP hadronization
Cheng Tao Yang, Johann Rafelski
We study bottom flavor abundance in the early Universe near to a temperature , the condition for hadronization of deconfined quark-gluon plasma…
Lepton Number and Expansion of the Universe
Cheng Tao Yang, Jeremiah Birrell, Johann Rafelski
We show that the non-integer effective number of neutrinos can be understood as an effect of lepton asymmetry in the early Universe carried by the Dirac ne…
Temperature Dependence of the Neutron Lifespan
Cheng Tao Yang, Jeremiah Birrell, Johann Rafelski
Current precision big bang nucleosynthesis (BBN) studies motivate us to revisit the neutron lifespan in the plasma medium of the early universe. The mechanism we explore is the Fer…
