  1. 0. Mainly axion cold dark matter from natural SUSY
    Prof. Eung Jin Chun (KIAS Seoul)
    04/06/2014 10:55
    By eschewing fine-tuning from the electroweak and QCD sectors of supersymmetry (natural supersymmetry or SUSY), and by invoking the Kim-Nilles solution to the SUSY mu problem, one is lead to models wherein the dark matter is comprised of a mixture of axions and higgsino-like WIMPs. Over a large range of Peccei-Quinn breaking scale f_a~ 10^9-10^{12} GeV, one then expects about 90-95% axion dark...

  3. 1. BICEP2 and its implications for cosmology and particle physics
    Dr Lorenzo Sorbo (University of Massachusetts, Amherst)
    04/06/2014 14:00
    In this talk, after a very brief description of inflation and its predictions for the properties Cosmic Microwave Background radiation, I will discuss the results by the BICEP2 collaboration, that recently claimed detection of the so-called primordial B modes in the CMB. In particular, my talk will focus on the implications that such a detection would have for inflationary model building and...

  4. 2. Fitting the Fermi-LAT GeV excess: on the importance of the propagation of electrons from dark matter

    An excess of gamma rays at GeV energies has been detected in the Fermi-LAT data. This signal comes from a narrow region around the Galactic Center and has been interpreted as possible evidence for light (30 GeV) dark matter particles. Focussing on the prompt gamma-ray emission, previous work found that the best fit to the data corresponds to annihilations proceeding into b quarks, with...

  5. 3. DM with supersymmetric triplets
    Dr Chiara Arina (IAP)
    04/06/2014 15:00
    The Triplet extension of the MSSM (TMSSM) alleviates the little hierarchy problem and provides a significant enhancement of the loop-induced diphoton rate of the lightest CP-even Higgs h. In this I will present the first computation of the h into Z + gamma decay. I will show that the rates of loop-induced decays are correlated and their signal strengths can rise up to 40% - 60% depending on...
