Charged lepton mixing and oscillations from neutrino mixing in the early Universe

D. Boyanovsky, C. M. Ho

Charged lepton mixing as a consequence of neutrino mixing is studied for two generations in the temperature regime in the early Universe. We state the gene…

Neutrino Oscillations in the Early Universe: A Real Time Formulation

C. M. Ho, D. Boyanovsky, H. J. de Vega

Neutrino oscillations in the early Universe prior to the epoch of primordial nucleosynthesis is studied by implementing real time non-equilibrium field theory methods. We focus on…

Quantum corrections to the inflaton potential and the power spectra from superhorizon modes and trace anomalies

D. Boyanovsky, H. J. de Vega, N. G. Sanchez

We obtain the effective inflaton potential during slow roll inflation by including the one loop quantum corrections to the energy momentum tensor from scalar curvature and tensor p…

Clarifying Inflation Models: Slow-roll as an expansion in 1/N_{efolds}

D. Boyanovsky, H. J. de Vega, N. G. Sanchez

Slow-roll inflation is studied as an effective field theory.We find as consistent form of the inflaton potential V(phi)=N M^4 w(phi/[sqrt{N}M_P]) where phi is the inflaton field, M…

Neutrino collective excitations in the Standard Model at high temperature

D. Boyanovsky

Neutrino collective excitations are studied in the Standard Model at high temperatures below the symmetry breaking scale. Two parameters determine the properties of the collective…

The Classical and Quantum Inflaton: the Precise Inflationary Potential and Quantum Inflaton Decay after WMAP

D. Boyanovsky, H. J. de Vega, N. G. Sanchez

We clarify classical inflaton models by considering them as effective field theories `a la Ginzburg-Landau. In this approach, the WMAP statement excluding the pure phi^4 potential…
