The primordial helium abundance from updated emissivities
Observations of metal-poor extragalactic H II regions allow the determination of the primordial helium abundance, Y_p. The He I emissivities are the foundation of the model of t...

The time evolution of the baryon asymmetry ($\frac{k{n}_{B}}{s}$) due to the interactions of a superheavy gauge boson (mass ${M}_{X}\ensuremath{\sim}{10}^{15}$ GeV, coupling str...
Evolution of cosmological baryon asymmetries. II. The role of Higgs bosons
The time evolution of the baryon asymmetry of the universe due to superheavy Higgs bosons is obtained by integrating the Boltzmann equations. The interactions included are decay...
