Title: Leptogenesis in the Neutrino Option

Abstract

We examine the compatibility between the Neutrino Option, in which the electroweak scale is generated by PeV mass type I seesaw Majorana neutrinos, and leptogenesis. We find the Neutrino Option is consistent with resonant leptogenesis. Working within the minimal seesaw scenario with two heavy Majorana neutrinos N_{1, 2}, which form a pseudo-Dirac pair, we explore the viable parameter space. We find that the Neutrino Option and successful leptogenesis are compatible in the cases of a neutrino mass spectrum with normal (inverted) ordering for 1.2 × 10⁶ < M(GeV) < 8.8 × 10⁶(2.4 × 10⁶ < M(GeV) < 7.4 × 10⁶), with M = (M₁ + M₂)/2 and M_{1, 2} the masses of N_{1, 2}. Successful leptogenesis requires that ΔM/M ≡ (M₂-M₁)/M~10^-8. We further show that leptogenesis can produce the baryon asymmetry of the Universe within the Neutrino Option scenario when the requisite CP violation in leptogenesis is provided exclusively by the Dirac or Majorana low energy CP violation phases of the PMNS matrix.

Baryogenesis via leptogenesis is investigated in a specific model of light neutrino masses and mixing angles. The latter was proposed on the basis of an assumed complex-extended scaling property of the neutrino Majorana mass matrix M {sub ν}, derived with a type-1 seesaw from a Dirac mass matrix m {sub D} and a heavy singlet neutrino Majorana mass matrix M {sub R} . One of its important features, highlighted here, is that there is a common source of the origin of a nonzero θ{sub 13} and the CP violating lepton asymmetry through the imaginary part of m {sub D} .more »« less

Leptogenesis with small violation of B−L

Journal Article Racker, J. ; Peña, Manuel ; Rius, Nuria - Journal of Cosmology and Astroparticle Physics

We analyze leptogenesis in the context of seesaw models with almost conserved lepton number, focusing on the L-conserving contribution to the flavoured CP asymmetries. We find that, contrary to previous claims, successful leptogenesis is feasible for masses of the lightest heavy neutrino as low as M{sub 1} ∼ 10{sup 6} GeV, without resorting to the resonant enhancement of the CP asymmetry for strongly degenerate heavy neutrinos. This lower limit renders thermal leptogenesis compatible with the gravitino bound in supersymmetric scenarios.

Aspects of thermal leptogenesis in braneworld cosmology

Journal Article Bento, M C ; Felipe, R Gonzalez ; Santos, N M. C. - Physical Review. D, Particles Fields

The mechanism of thermal leptogenesis is investigated in the high-energy regime of braneworld cosmology. Within the simplest seesaw framework with hierarchical heavy Majorana neutrinos, we study the implications of the modified Friedmann equation on the realization of this mechanism. In contrast with the usual leptogenesis scenario of standard cosmology, where low-energy neutrino data favors a mildly strong washout regime, we find that leptogenesis in the braneworld regime is successfully realized in a weak washout regime. Furthermore, a quasidegenerate light neutrino mass spectrum is found to be compatible with this scenario. For an initially vanishing heavy Majorana neutrino abundance, thermal leptogenesismore »« less

Phased breaking of {mu}-{tau} symmetry and leptogenesis

Journal Article Ahn, Y H ; Kim, C S ; Kang, Sin Kyu ; ... - Physical Review. D, Particles Fields

Nonvanishing U{sub e3} has been theoretically related to a certain flavor symmetry breaking in the neutrino sector. We propose a scenario to break the {mu}-{tau} symmetry so as to accommodate the nonvanishing U{sub e3}. Our scenario is constructed in the context of a seesaw model, and the {mu}-{tau} symmetry breaking is achieved by introducing a CP phase in the Dirac Yukawa matrix. We also show how the deviation of {theta}{sub 23} from the maximal mixing and nonvanishing U{sub e3} depend on the CP phase. Neutrino mixings and the neutrino mass-squared differences are discussed, and the amplitude in neutrinoless double betamore »« less

Leptonic $C P$ violation and leptogenesis in minimal supersymmetric $SU (4)_{c} \times SU (2)_{L} \times SU (2)_{R}$

Journal Article Okada, Nobuchika ; Shafi, Qaisar - Physical Review. D.

We consider a supersymmetric SU(4)_c × SU(2)_L × SU(2)_R model with a minimal number of Higgs multiplets and Dirac and Majorana CP-violating phases in the neutrino flavor mixing matrix. The model incorporates the charged fermion masses and quark mixings, and uses type I seesaw to explain the solar and atmospheric neutrino oscillations. With the neutrino oscillation data of two mass squared differences and three flavor mixing angles, we employ thermal leptogenesis and the observed baryon asymmetry to find the allowed regions for the Dirac and Majorana phases. For a normal neutrino mass hierarchy, we find that the observed baryon asymmetrymore »« less
