  1. 11. Dark stuff (review talk)
    Dr Malcolm Fairbairn (King's College London)
    15/05/2012 09:30
    I will (extremely) briefly review the evidence for dark matter and then the ongoing efforts to detect it using indirect and direct detection. I will talk about recent developments in indirect detection including a couple of potential signals from Fermi and some recent pessimistic predictions from N-body simulations. I will then review the ongoing search for dark matter via direct detection. ...

  2. 18. Neutralino relic density with Next to Leading Order (co)annihilation cross-section
    M. Quentin Le Boulc'h (LPSC)
    15/05/2012 10:10
    The relic density of Dark Matter in the Universe imposes today one of the most stringent constraints on new physics models such as the Minimal Supersymmetric Standard Model (MSSM). The most recent analysis of the WMAP collaboration has already reached an accuracy of 3%, and the upcoming results obtained with the Planck satellite will be even more precise. It is therefore mandatory for the...

  3. 52. Mixed sneutrino dark matter in light of recent experimental results
    Béranger DUMONT (LPSC Grenoble)

  4. 21. Probing the supersymmetric inflaton and dark matter link
    M. Jonathan Da Silva (Laboratoire d'Annecy-Le-Vieux de Physique Théorique)
    15/05/2012 11:30
    In this talk I will present a study on the NUHM2 supersymmetric model where both the cosmic inflation and the observed dark matter abundance can be explained, with a Higgs boson mass in the range favoured by the latest LHC data. The two inflaton candidates LLe and udd are embedded within the MSSM therefore their decay naturally excites all the relevant degrees of freedom which thermalizes the...

  5. 25. Neutrinos are not in a rush
    Dr philippe brax (IPHT Saclay)
    15/05/2012 11:55
    I will describe how neutrinos could go faster than the speed of light in a dense environment if gravity were modified by a scalar field. I will show that the speed difference would almost always be unobservable for natural values of the couplings of scalars to matter.

  6. 17. Lepton flavour violation in the inverse seesaw
    Cedric Weiland (LPT Orsay)
    15/05/2012 12:20
    The inverse seesaw is a very appealing mechanism to generate neutrino masses since it provides natural neutrino Yukawa couplings ($Y_\nu \sim O(1)$) and a seesaw scale close to the electroweak one, thus within LHC reach. In a previous work (arXiv:1111.5836) where we embedded the inverse seesaw in a supersymmetric extension of the Standard Model (MSSM), we have highlighted that the...
