A bstractWe show how knowledge of the cold dark matter (CDM) density can be used, in conjunction with measurements of the parameters of a scenario for beyond the Standard Model (BSM) physics, to provide information about the evolution of the Universe before Big Bang Nucleosynthesis (BBN). As examples of non-standard evolution, we consider models with a scalar field that may decay into BSM particles, and quintessence models. We illustrate our calculations using various supersymmetric models as… 
Neutralino dark matter in scenarios with early matter domination
A bstractWe investigate the production of neutralino dark matter in a cosmological scenario featuring an early matter dominated era ending at a relatively low reheating temperature. In such scenarios
Reconstructing non-standard cosmologies with dark matter
Once dark matter has been discovered and its particle physics properties have been determined, a crucial question rises concerning how it was produced in the early Universe. If its thermally averaged
Gravitational production of vector dark matter
A model of vector dark matter that communicates with the Standard Model only through gravitational interactions has been investigated. It has been shown in detail how does the canonical quantization
Phenomenological Constraints on Anomaly-Free Dark Matter Models : arXiv
We study minimal benchmark models of dark matter with an extra anomaly-free U(1)' gauge boson Z'. We find model parameters that give rise to the correct cosmological dark matter density while evading
Self-interacting dark matter without prejudice
The existence of dark matter particles that carry phenomenologically relevant self-interaction cross sections mediated by light dark sector states is considered to be severely constrained through a
Scalar multiplet dark matter in a fast expanding Universe: Resurrection of the desert region
We examine the impact of a faster expanding Universe on the phenomenology of scalar dark matter (DM) associated with SU(2)L multiplets. Earlier works with radiation dominated Universe have reported
Phenomenology of doublet-triplet fermionic dark matter in nonstandard cosmology and multicomponent dark sectors
We consider the doublet-triplet fermionic model in the scheme of the custodial limit when the dark matter (DM) candidate is pure doublet and lies at the electroweak scale. %, which is a simplified
The First Three Seconds: a Review of Possible Expansion Histories of the Early Universe
It is commonly assumed that the energy density of the Universe was dominated by radiation between reheating after inflation and the onset of matter domination 54,000 years later. While the abundance
Dark matter and early Universe
Big-Bang nucleosynthesis (BBN) represents one of the earliest phenomena that can lead to observational constraints on the early Universe properties. It is well-known that many important mechanisms
A dark clue to seesaw and leptogenesis in singlet doublet scenario with (non)standard cosmology
We present an appealing alternative scenario of leptogenesis assisted by dark sector which leads to the baryon asymmetry of the Universe satisfying all theoretical and experimental constraints. We


Dark matter production in an early matter dominated era
We investigate dark matter (DM) production in an early matter dominated era where a heavy long-lived particle decays to radiation and DM. In addition to DM annihilation into and thermal DM production
Supersymmetric Dark Matter
Robustness of dark matter constraints and interplay with collider searches for New Physics
A bstractWe study the implications of dark matter searches, together with collider constraints, on the phenomenological MSSM with neutralino dark matter and focus on the consequences of the related
Supersymmetric Dark Matter
A review of supersymmetric dark matter in minimal supergravity unification with R-parity invariance and with radiative breaking of the electro-weak symmetry is given. The analysis shows the lightest
SUSY constraints, relic density, and very early universe
The sensitivity of the lightest supersymmetric particle relic density calculation to different cosmological scenarios is discussed. In particular, we investigate the effects of modifications of the
When the universe expands too fast: relentless dark matter
We consider a modification to the standard cosmological history consisting of introducing a new species ϕ whose energy density red-shifts with the scale factor a like ρϕ ∝ a−(4+n). For 0n>, such a
Tracking quintessence and cold dark matter candidates
We study the generation of a kination-dominated phase in the context of a quintessential model with an inverse-power-law potential and a Hubble-induced mass term for the quintessence field. The
Thermal relics: Do we know their abundances?
Three nonstandard possibilities for the Universe at the time a species’ abundance froze in are considered: energy density dominated by shear, energy density dominance of the scalar field that sets the gravitational constant in a Brans-Dicke-Jordan cosmological model, and a component of the energy density at early times with a very stiff equation of state.
Quintessential kination and cold dark matter abundance
The generation of a kination-dominated phase by a quintessential exponential model is investigated and the parameters of the model are restricted so that a number of observational constraints
