Non-minimal sneutrino inflation, Peccei-Quinn phase transition and non-thermal leptogenesis

Journal Article Pallis, C. ; Toumbas, N., E-mail: kpallis@auth.gr, E-mail: nick@ucy.ac.cy - Journal of Cosmology and Astroparticle Physics

We consider a phenomenological extension of the minimal supersymmetric standard model which incorporates non-minimal chaotic inflation, driven by a quartic potential associated with the lightest right-handed sneutrino. Inflation is followed by a Peccei-Quinn phase transition based on renormalizable superpotential terms, which resolves the strong CP and μ problems of the minimal supersymmetric standard model provided that one related parameter of the superpotential is somewhat small. Baryogenesis occurs via non-thermal leptogenesis, which is realized by the inflaton decay. Confronting our scenario with the current observational data on the inflationary observables, the baryon assymetry of the universe, the gravitino limit on themore »« less

F-term hybrid inflation followed by a Peccei-Quinn phase transition

Journal Article Lazarides, G ; Pallis, C - Physical Review. D, Particles Fields

We consider a cosmological setup, based on renormalizable superpotential terms, in which a superheavy scale F-term hybrid inflation is followed by a Peccei-Quinn phase transition, resolving the strong CP and {mu} problems of the minimal supersymmetric standard model. We show that the field which triggers the Peccei-Quinn phase transition can remain after inflation well above the Peccei-Quinn scale thanks to (i) its participation in the supergravity and logarithmic corrections during the inflationary stage and (ii) the high reheat temperature after the same period. As a consequence, its presence influences drastically the inflationary dynamics and the universe suffers a second periodmore »« less

Peccei-Quinn symmetry for Dirac seesaw and leptogenesis

Journal Article Gu, Pei-Hong - Journal of Cosmology and Astroparticle Physics

We extend the DFSZ invisible axion model to simultaneously explain small Dirac neutrino masses and cosmic matter-antimatter asymmetry. After the Peccei-Quinn and electroweak symmetry breaking, the effective Yukawa couplings of the Dirac neutrinos to the standard model Higgs scalar can be highly suppressed by the ratio of the vacuum expectation value of an iso-triplet Higgs scalar over the masses of some heavy gauge-singlet fermions, iso-doublet Higgs scalars or iso-triplet fermions. The iso-triplet fields can carry a zero or nonzero hypercharge. Through the decays of the heavy gauge-singlet fermions, iso-doublet scalars or iso-triplet fermions, we can obtain a lepton asymmetry inmore »« less

Affleck-Dine leptogenesis with varying Peccei-Quinn scale

Journal Article Bae, Kyu Jung ; Baer, Howard A. ; Hamaguchi, Koichi ; ... - Journal of High Energy Physics (Online)

The Affleck-Dine leptogenesis scenario along the LH _u flat direction is recon- sidered. It is known that successful Affleck-Dine leptogenesis requires that the lightest neutrino mass is extremely small. This situation can be significantly relaxed if the neutrino mass in the early universe is different from the present one. We consider a supersymmetric Dine-Fischler-Srednicki-Zhitnitsky (DFSZ) type model, which provides a solution to the strong CP problem and generates a SUSY μ-term and right-handed neutrino masses. If the PQ scale during lepton number generation is much larger than the present value, leptogenesis is very efficient so that enough baryon number canmore »« less

Dynamics of Peccei-Quinn breaking field after inflation and axion isocurvature perturbations

Journal Article Harigaya, Keisuke ; Ibe, Masahiro ; Kawasaki, Masahiro ; ... - Journal of Cosmology and Astroparticle Physics

The Peccei-Quinn mechanism suffers from the problem of the isocurvature perturbations. The isocurvature perturbations are suppressed if the Peccei-Quinn breaking scale is large during inflation. The oscillation of the Peccei-Quinn breaking field after inflation, however, leads to the formation of domain walls due to the parametric resonance effect. In this paper, we discuss the evolution of the Peccei-Quinn breaking field after inflation in detail, and propose a model where the parametric resonance is ineffective and hence domain walls are not formed. We also discuss consistency of our model with supersymmetric theory.
