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.

TL;DR: In the see-saw model, the baryon asymmetry of the Universe can be generated by the decay of the lightest right-handed neutrino, νR as discussed by the authors.

Running Kinetic Inflation
TL;DR: In this article, a running kinetic inflation model was proposed in which the inflaton potential becomes flat due to rapid growth of the kinetic term at large inflaton field values, leading to many interesting phenomena.
Inflation induced SUSY breaking and flat vacuum directions
TL;DR: In this paper, it was shown that under general assumptions all gauge nonsinglet fields, parameterizing flat directions (and in particular squarks and sleptons), get large radiative masses which are related to the value of the Hubble constant (H ) and to the expectation value of inflaton field.
Structure of the High Temperature Gauge Ground State and Electroweak Production of the Baryon Asymmetry
TL;DR: In this article, the authors investigated the connection of the baryon asymmetry of the universe (BAU) with the Chern-Simons structure of the ground state of gauge theories at high temperatures.
Affleck–Dine leptogenesis via multiscalar evolution in a supersymmetric seesaw model
Masato Senami,Tsutomu Takayama +1 more
TL;DR: In this article, a leptogenesis scenario in a supersymmetric standard model with right-handed neutrinos is reconsidered, where lepton asymmetry is produced in the condensate of a right-hand sneutrino via the Affleck-Dine mechanism.
Unified gauge theories and the baryon number of the universe
TL;DR: In this paper, the dominance of matter over antimatter in the present universe is a consequence of baryon-number nonconserving reactions in the very early fireball, and a computation in specific SU(5) models gives a small ratio of Baryon to photon-number density in rough agreement with observation.
