20. Loop contributions to cosmological correlations and experimental constrains on chaotic inflation
Jae Sik Lee
After a brief introduction to CP violation in the MSSM, we discuss how to probe the CP-violating mixing in the neutral Higgs-boson sector at the LHC. We observe that there is an interesting possibility to have the lightest relic neutralino as light as 2.9 GeV.

Leptogenesis via right-handed neutrino decays is a successful mechanism to explain the matter-antimatter asymmetry of the Universe. I will discuss some recent developments, in particular flavour and memory effects.

We find that there is no supersymmetric flavor/CP problem, mu-problem, cosmological moduli/gravitino problem or dimension four/five proton decay problem in a class of supersymmetric theories with O(1) GeV gravitino mass. The cosmic abundance of the non-thermally produced gravitinos naturally explains the dark matter component of the universe. A mild hierarchy between the mass scale of...
The Planck satellite, to be launched in 2008, is designed for measuring CMB temperature and polarization anisotropies with much better precision than the -already impressive- WMAP experiment. In this seminar, I will present the expected sensitivity of Planck to the parameters describing dark matter, dark energy, inflation, relic neutrinos, etc., which are also of great interest for...

We propose a renormalizable (SUSY) grand unified theory where the neutrino masses are generated through type III and type I seesaw mechanisms. Several phenomenological and cosmological aspects of this proposal are discussed.
We discuss the opportunities in our search for `new physics' beyond the standard model offered by present and future flavour experiments. We show the interplay and complementarity of collider and flavour physics by some examples. Within this talk we focus on rare B and kaon decays. Moreover, we briefly discuss the restrictive role of long-distance strong interactions in flavour...
A key ingredient in assessing whether or not a stable neutralino can explain the observed dark matter of the universe is the mass of the neutralino. For many SUSY decay chains, only mass differences can be well determined by conventional techniques leaving a large uncertainty in the absolute mass scale and therefore in the mass of the LSP neutralino itself. I describe a technique that can...
The dark matter candidate in the left-right Twin Higgs models falls in to the category of inert Higgs doublet models. We analysed the dark matter relic density and its direct and indirect detection potential.
I will review the present status of the analyses of the possibility of implementing the mechanism of generation of the baryon-antibaryon asymmetry at the electroweak scale, in supersymmetric extensions of the Standard Model. I will discuss the interrelation of this mechanism with the origin of dark matter, as well possible tests of these scenarios at the Tevatron and the LHC, as well as in...

We consider supersymmetric theories where the gravitino is the lightest superparticle (LSP) and a charged scalar lepton the next-to-lightest superparticle (NLSP). Such a scenario can lead to spectacular signatures at the LHC, which we illustrate with several examples. A gravitino LSP can be the dominant component of dark matter. In the case of small R-parity breaking, it may first be...
34. The observed properties of dark matter on small astrophysical scales, and the number of small satellites
New dynamical studies and discovery searches for the smallest dark matter dominated galaxies will be presented. Dark matter in dSph galaxies has a mean volume mass density within the stellar distribution which always has a very low value of about 5GeV/c^2 cm^-3. The mass profiles appear cored, not cusped as predicted by Cold DM models. Galaxies are embedded in dark matter halos with...
I will discuss the connection among Higgs Physics, Flavour Physics and Cosmology in Supersymmetric Models. I will highlight the impact of radiative corrections to the Higgs-fermion couplings which can lead to relevant Flavour concerving and FCNC effects. This will allow me to show the interplay between direct Higgs searches at the Tevatron and the LHC and the impact of present and projected...

45. Predictive model for dark matter, dark energy, neutrino masses and leptogenesis at the TeV scale
If the lightest neutralino is a stable thermal relic from the Big Bang, thus comprising dark matter (DM) in the Universe, its relic abundance can be used to severely constrain the parameter space of supersymmetric models. For instance, in the paradigm mSUGRA model, each DM allowed region gives rise to distinct signatures for new physics at the LHC. We explore an array of...

Warped compactifications provide a mechanism for generating a hierarchy of physical scales. Strongly warped regions (throats) are also ubiquitous in compactifications with stabilized moduli. In this talk, we describe some recent attempts to construct string inflationary models using warped throats, the CMB signatures of these models, and how differences in the shape of the extra...
It has recently been proposed to replace the anthropic principle with a more objective criterion: the likelihood of creating observers is proportional to the amount of entropy production within a causally connected region of the universe. This "entropic principle" does a better job of predicting the value of the cosmological constant than does its anthropic predecessor, and it is...
Part 1: Discussion of recent papers/events ***everybody is invited to contribute*** Part 2: Talk by Tomas Blazek
The time evolution of a cosmological scalar field can be stopped by an increasing mass of the neutrinos. This leads to a transition from a cosmological scaling solution with dynamical dark energy at early time to a cosmological constant dominated universe at late time. The trigger for the transition is set at the time when the neutrinos become non-relativistic. This is a possible...
