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.

The Moduli and Gravitino (non)-Problems in Models with Strongly Stabilized Moduli
TL;DR: In this article, it was shown that the amplitude of moduli oscillations is severely limited by strong stabilization, and that modulus oscillations may then never come to dominate the energy density of the universe.

TL;DR: In this paper, the authors argue that the appropriate framework for cosmological inflation is that of no-scale supergravity, and show how to use supersymmetry in the context of supergravity.

A Solution to the Coincidence Puzzle of \Omega_{B} and \Omega_{DM}
TL;DR: In this article, it was shown that a class of Affleck-Dine baryogenesis directly relates the observed mass density of baryons to that of dark matter, i.e., it is determined by low energy parameters, except for an O(0.1) effective CP-violating phase.

Reheating processes after Starobinsky inflation in old-minimal supergravity
TL;DR: In this article, the Starobinsky model embedded in the old-minimal supergravity was considered and its cosmological consequences in the reheating process were investigated. But the authors considered a simple model of supersymmetry breaking sector, and obtained limits on the masses of gravitino and supersymmetric breaking field.
Axion Kinetic Misalignment and Parametric Resonance from Inflation

TL;DR: In this article, the effects of inflation on the Peccei-Quinn symmetry breaking field and parametric resonance have been investigated, and it was shown that a significant portion of the allowed parameter space predicts rare kaon decays, and suppression of structure formation on small scales.
