  1. 221. Connections between colliders and cosmology in the nMSSM

    In a minimal singlet extension of the MSSM, the nMSSM, both the problem of baryogenesis and dark matter can be elegantly solved without large fine-tuning. As a result of these cosmological constraints, the parameter space of the nMSSM is strongly reduced, and the model predicts that a number of new Higgs and supersymmetric particles are within reach of the LHC and ILC. Here the...

    We examine the phenomenology of recently constructed models where moduli-mediated contributions to soft SUSY breaking (SSB) parameters are comparable to those from the Weyl anomaly. This structure of the soft terms arises in models of string compactification with fluxes, where the addition of an anti-brane leads to an uplifting potential which yields a de Sitter Universe and supersymmetry...

  3. 197. Non-Universal gaugino masses and implications on the Dark Matter and Higgs searches

    Non-universal boundary conditions in grand unified theories can lead to non-universal gaugino masses at the unification scale. In R-parity preserving theories the lightest supersymmetric particle is a natural candidate for the dark matter. We have studied the composition of the lightest neutralino in non-universal gaugino mass cases from the SU(5), and implications on the dark matter. In...

  4. 257. Lightest neutralino in the MNSSM
    Dr Roman Nevzorov (University of Glasgow)

    Cosmology and Astrophysics
    Parallel Talk
    In the minimal supersymmetric standard model (MSSM) and Minimal Non--minimal Supersymmetric Standard Model (MNSSM) the lightest neutralino can be absolutely stable providing a good candidate for the cold dark matter component of the Universe. At the same time the \mu problem of the MSSM is solved within MNSSM without accompanying problems related with the appearance of domain walls. In...

  5. 297. Mixed-sneutrino dark matter at the LHC

    Cosmology and Astrophysics
    Parallel Talk
    In supersymmetric theories with right-handed neutrinos, new possibilities open up for dark matter. I will discuss a scenario in which right-handed sneutrinos with weak-scale masses mix with left-handed sneutrinos through weak-scale A terms. In this case the lightest sneutrino mass eigenstate is a viable dark matter candidate. After discussing the constraints on this model from requiring...

  6. 343. Dark matter in SUGRA models and the LHC
    Prof. David Toback (Texas A&M University)

    Cosmology and Astrophysics
    Parallel Talk
    The minimal supergravity (mSUGRA) model explains the observed dark matter content of the universe and requires the stau-neutralino co-annihilation mechanism in the early universe for a region of supersymmetry parameter space. This co-annihilation region is characterized by a small mass difference (~5-15 GeV) between the lightest stau and the lightest neutralino. An accurate measurement ...
