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.

PyCOOL - a Cosmological Object-Oriented Lattice code written in Python
TL;DR: A graphics processing unit (GPU) accelerated Python program called PyCOOL that solves the evolution of scalar fields in a lattice with very precise symplectic integrators and is found that the program is not only accurate but also very fast.
Kinetic theory for scalar fields with nonlocal quantum coherence
TL;DR: In this article, the authors derived quantum kinetic equations for scalar fields undergoing coherent evolution either in time (coherent particle production) or in space (quantum reflection) and showed that in systems with certain space-time symmetries, quantum coherence manifests itself in the form of new spectral solutions for the 2-point correlation function.

Regulating the Baryon Asymmetry in No-Scale Affleck-Dine Baryogenesis ∗
TL;DR: In this article, the authors show that the observed BAU can be suppressed by dilution from inflaton or moduli decay, GUT non-flatness of the vev direction, and higher dimensional operators in both GUT models and the MSSM.
