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 expansion rate and of the entropy content in the Early Universe. These effects, even with no observational consequences, can still drastically modify the relic density constraints on the SUSY parameter space. We suggest general parametrizations to evaluate such effects, and derive also constraints… 

Relic density and future colliders: inverse problem(s)

Relic density calculations are often used to constrain particle physics models, and in particular supersymmetry. We will show that the presence of additional energy or entropy before the Big-Bang

Anomaly mediated SUSY breaking scenarios in the light of cosmology and in the dark (matter)

Anomaly mediation is a popular and well motivated supersymmetry breaking scenario. Different possible detailed realisations of this set-up are studied and actively searched for at colliders. Apart

LHC and ILC Data and the Early Universe Properties

With the start-up of the LHC, we can hope to find evidences for new physics beyond the Standard Model, and particle candidates for dark matter. Determining the parameters of the full underlying

Leptogenesis, gravitino dark matter, and entropy production

Many extensions of the standard model predict superweakly interacting particles, which typically have to decay before big bang nucleosynthesis. The entropy produced in the decays may help to

Dilaton dominance relaxes LHC and cosmological constraints in supersymmetric models

A bstractIt has been pointed out recently that the presence of dilaton field in the early Universe can dilute the neutralino dark matter (DM) abundance, if Universe is not radiation dominated at DM

Radiative corrections to neutralino annihilation: Recent developments

Evaluating the relic density of dark matter is an interestin g possibility to constrain the parameter space of new physics models. However, this calculation is affected by several sources of

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

Towards a consistent cosmology with supersymmetry and leptogenesis

We study the cosmological interplay between supersymmetry, thermal leptogenesis as the origin of matter and the Peccei-Quinn mechanism as solution to the strong CP problem. We investigate to what

The lithium problem: new insight in the big bang nucleosynthesis (BBN) beyond the standard model

The production of the light elements in the framework of the standard Big Bang nucleosynthesis model (SBBN) matches the observed abundances except in case of 7Li, where observations lie a factor

Gravitino dark matter and the lithium primordial abundance within a pre-BBN modified expansion

We present supersymmetric scenarios with gravitino LSP and stau NLSP in the case of a non-standard model of cosmology with the addition of a dark component in the pre-BBN era. In the context of the

Supersymmetric Dark Matter and the Reheating Temperature of the Universe

Since the thermal history of the Universe is unknown before the epoch of primordial nucleosynthesis, the largest temperature of the radiation dominated phase (the reheating temperature) might have

SUSY dark matter and quintessence

We investigate the enhancement of neutralino relic density in the context of a realistic cosmological scenario with quintessence. The accurate relic density computation we perform allows us to be

Dark matter relic abundance and scalar-tensor dark energy

Scalar-tensor theories of gravity provide a consistent framework to accommodate an ultralight quintessence scalar field. While the equivalence principle is respected by construction, deviations from

Largest temperature of the radiation era and its cosmological implications

The thermal history of the universe before the epoch of nucleosynthesis is unknown. The maximum temperature in the radiation-dominated era, which we will refer to as the reheat temperature, may have

Effect of a late decaying scalar on the neutralino relic density

If the energy density of the Universe before nucleosynthesis is dominated by a scalar field {phi} that decays and reheats the plasma to a temperature T{sub RH} smaller than the standard neutralino

Requirements on collider data to match the precision of WMAP on supersymmetric dark matter.

If future colliders discover supersymmetric particles and probe their properties, one could predict the dark matter density of the Universe and would constrain cosmology with the help of precision

Cosmological Constraints on Late-time Entropy Production

We investigate cosmological effects concerning the late-time entropy production due to the decay of non-relativistic massive particles. The thermalization process of neutrinos after the entropy
