Abstract: A new mechanism for baryogenesis is proposed. It is argued that, after inflation, the scalar quarks and leptons of a supersymmetric GUT may have large expectation values. The subsequent evolution of such a system is shown to generate a significant baryon density. For typical values of the parameters, n B / n γ may be as large as 10 3 .

Particle dark matter: Evidence, candidates and constraints
TL;DR: The current status of particle dark matter, including experimental evidence and theoretical motivations, including direct and indirect detection techniques, is discussed in this paper. But the authors focus on neutralinos in models of supersymmetry and Kaluza-Klein dark matter in universal extra dimensions.

Baryogenesis without grand unification
TL;DR: In this article, a mechanism to generate cosmological baryon number excess without resorting to grand unified theories is proposed, where the lepton number excess originating from Majorana mass terms may transform into the number excess through the unsuppressed baryone number violation of electroweak processes at high temperatures.

TL;DR: Euclid is a European Space Agency medium-class mission selected for launch in 2020 within the cosmic vision 2015-2025 program as discussed by the authors, which will explore the expansion history of the universe and the evolution of cosmic structures by measuring shapes and red-shift of galaxies as well as the distribution of clusters of galaxies over a large fraction of the sky.
Low-energy phenomenology of superstring-inspired E6 models
TL;DR: In this paper, the authors survey the low-energy phenomenological implications of superstring-inspired E 6 models and present experimental limits on these particles from both accelerator and non-accelerator data.

Thermal Effects And Flat Direction Baryogenesis
TL;DR: In this paper, a detailed numerical study of the influence of thermal effects on the original picture of AD baryogenesis is provided. But the results are limited to some cases, and they are not applicable to all cases.
Revisiting the minimal chaotic inflation model
TL;DR: In this article, it was shown that the inflaton potential is effectively flattened at a large inflaton field value in the presence of such a scalar field, which is consistent with recent observations of the cosmic microwave background fluctuation.
Monopoles, axions and intermediate mass dark matter

TL;DR: In this article, a solution to the cosmological problem encountered in (supersymmetric) grand unified theories due to copious monopole production at the end of hybrid inflation is presented.
Inflation and Leptogenesis in a $U(1)$-enhanced supersymmetric model
TL;DR: In this paper, a supersymmetric extension of the standard model (SM) was proposed to explain inflation and leptogenesis by adding neutrinos to the original standard model.
Opening the window to the cogenesis with Affleck-Dine mechanism in gravity mediation
TL;DR: In this paper, the authors revisited the scenario of baryon and dark matter cogenesis from Q ball in gravity mediation and found that the successful cogenesis takes place when a wino with mass 400-600 GeV is dark matter.
