Prof. Lisa Everett Everett (University of Wisconsin)31/07/2007, 14:20Cosmology and AstrophysicsParallel TalkKination-dominated quintessence scenarios can provide an intriguing connection between thermal WIMP dark matter and dark energy which can be tested at forthcoming and future colliders. We present the results of our investigation of the implications of such nonstandard cosmological models for neutralino dark matter in the MSSM, focusing on the role of the ILC in determining the...Go to contribution page

Mr Mathias Garny (Max Planck Institute for Nuclear Physics)31/07/2007, 14:40Cosmology and AstrophysicsParallel TalkWe investigate the role of quantum corrections within the quintessence dark energy scenario in the framework of low-energy effective field theory. In this framework, the quintessence field, which can drive an accelerated cosmic expansion, is viewed as arising from a high-energy theory, which is governed by a UV-scale of the order of the GUT or Planck scales. We study the low-energy...Go to contribution page

Prof. Daniel Chung (University of Wisconsin)31/07/2007, 15:00Cosmology and AstrophysicsParallel TalkA new class of constraint system applicable to continuous covariant field theories is explained. When coupled to gravity, it modifies the constraints of Einstein equations. Cosmological implications are also presented.Go to contribution page

Dr Thomas Dent (Heidelberg)31/07/2007, 15:20Cosmology and AstrophysicsParallel TalkWe analyze the effect of variation of fundamental couplings and mass scales on primordial nucleosynthesis in a systematic way. The first step establishes the response of primordial element abundances to the variation of a large number of nuclear physics parameters, including nuclear binding energies. We find a strong influence of the $n-p$ mass difference (for the \hefo\ abundance), of the...Go to contribution page

Kazunari Shima31/07/2007, 15:40Cosmology and AstrophysicsParallel TalkMSSM and SUSY GUTs are the candidates of theoretical models beyond SM. However the naive extensions of SM allow many arbitrary parameters and many unobserved elementary (SUSY) particles, which lose simplicity of Nature and the predictive powers. In this talk, firstly we review quickly the NLSUSYGR which describes the NLSUSY invariant coupling of (Nambu-Godldstone...Go to contribution page
