GUT Scale And Leptogenesis From 5D Inflation

We discuss a five dimensional inflationary scenario based on a supersymmetric SO(10) model compactified on S/(Z2 × Z ′ 2). Inflation is implemented through scalar potentials on four dimensional branes, and a brane-localized Einstein-Hilbert term plays an essential role. The orbifold boundary conditions break the SO(10) gauge symmetry to SU(4)c×SU(2)L×SU(2)R (≡ H). The inflationary scenario yiel...

A simple 5D SO(10) GUT and sparticle masses

Simple supersymmetric SO(10) GUT in five dimensions is proposed, in which the fifth dimension is compactified on the S/(Z2 × Z ′ 2) orbifold with two inequivalent branes at the orbifold fixed points. In this model, all matter and Higgs multiplets reside on one brane (PS brane) where the Pati-Salam (PS) symmetry is manifest, while only the SO(10) gauge multiplet resides on the bulk. The supersym...

Spontaneous Non-thermal Leptogenesis in High-scale Inflation Models

We argue that a non-thermal leptogenesis occurs spontaneously, without direct couplings of the inflaton with right-handed neutrinos, in a wide class of high-scale inflation models such as the chaotic and hybrid inflation. It is only a finite vacuum expectation value of the inflaton, or more precisely, a linear term in the Kähler potential, that is a prerequisite for the spontaneous non-thermal ...

Flavor effects in thermal leptogenesis

We review recent developments in leptogenesis on flavor effects. Their account discloses an important connection between the matter-antimatter asymmetry of the Universe and CP violation at low energies. Besides, they modify the upper bound on the neutrino masses holding in the unflavored case. In this respect, it is important to identify the exact condition for flavor effects to be relevant and...

Non-thermal Leptogenesis from the Heavier Majorana Neutrinos

We investigate a scheme for making leptogenesis by means of the CP violating decays of the seesaw Majorana neutrinos proposed by Fukugita and Yanagida. However, in order to avoid the wash-out of the produced lepton number we propose the production of the Majorana neutrinos to occur non-thermally and sufficiently late. After this time, in consequence, the B − L (baryon minus lepton) quantum numb...
