  • Effect of low mass dark matter particles on the Sun

    Article, Preprint English OPEN
    Taoso, M; Iocco, F; Meynet, G; Bertone, G; Eggenberger, P; (2010)
    We study the effect of dark matter (DM) particles in the Sun, focusing, in particular, on the possible reduction of the solar neutrinos flux due to the energy carried away by DM particles from the innermost regions of the Sun, and to the consequent reduction of the temp...
  • Enhancing $l_i \to 3 l_j$ with the $Z^0$-penguin

    Article, Preprint English OPEN
    Hirsch, M.; Staub, F.; Vicente, A.; (2012)
    Lepton flavor violation has been observed in neutrino oscillations. For charged lepton flavor violation decays only upper limits are known, but sizable branching ratios are expected in many neutrino mass models. High-scale models, such as the classical supersymmetric se...
  • MSSM: cornered and correlated

    Article, Preprint English OPEN
    Haisch, Ulrich; Mahmoudi, Farvah; (2012)
    Inspired by the latest results of ATLAS and CMS on the search for the standard model (SM) Higgs scalar, we discuss in this article the correlations between Higgs-boson properties, low-energy observables, such as B -> X_sgamma, B_s -> mu^+mu^-, and (g-2)_mu, and the dark...
  • Goldstino and sgoldstino in microscopic models and the constrained superfields formalism

    Article, Preprint English OPEN
    Antoniadis, I.; Dudas, E.; Ghilencea, D. M.; (2012)
    We examine the exact relation between the superconformal symmetry breaking chiral superfield (X) and the goldstino superfield in microscopic models of an arbitrary Kahler potential (K) and in the presence of matter fields. We investigate the decoupling of the massive sg...
  • New techniques for chargino-neutralino detection at LHC

    Article, Preprint English OPEN
    Cabrera, Maria Eugenia; Casas, J. Alberto; Zaldivar, Bryan; (2012)
    The recent LHC discovery of a Higgs-like boson at 126 GeV has important consequences for SUSY, pushing the spectrum of strong-interacting supersymmetric particles to high energies, very difficult to probe at the LHC. This gives extra motivation to study the direct produ...
  • Liberating Higgs couplings in supersymmetry

    Article, Preprint English OPEN
    Petersson, Christoffer; Romagnoni, Alberto; Torre, Riccardo; (2013)
    In the MSSM, the Higgs couplings to down-type quarks and leptons, normalized with respect to their corresponding Standard Model values, coincide at tree-level and this degeneracy is only slightly broken at the quantum level. Motivated by the latest results of the Higgs ...
  • Naturally split supersymmetry

    Article, Preprint English OPEN
    Bhattacharyya, Gautam; Ray, Tirtha Sankar; (2012)
    Nonobservation of superparticles till date, new Higgs mass limits from the CMS and ATLAS experiments, WMAP constraints on relic density, various other low energy data, and the naturalness consideration, all considered simultaneously imply a paradigm shift of supersymmet...
  • Holographic perfect fluidity, Cotton energy-momentum duality and transport properties

    Article, Preprint English OPEN
    Mukhopadhyay, Ayan; Petkou, Anastasios C.; Petropoulos, P. Marios; Pozzoli, Valentina; Siampos, Konstadinos; (2014)
    We investigate background metrics for 2 + 1-dimensional holographic theories where the equilibrium solution behaves as a perfect fluid, and admits thus a thermodynamic description. We introduce stationary perfect-Cotton geometries, where the Cotton-York tensor takes the...
  • Quantum corrections to broken N=8 supergravity

    Article, Preprint English OPEN
    Dall'Agata, Gianguido; Zwirner, Fabio; (2012)
    We show that the one-loop effective potential of spontaneously broken N=8 supergravity is calculable and finite at all classical four-dimensional Minkowski vacua without tachyons in the spectrum. The reason is that the supertraces of the quadratic and quartic mass matri...
  • Spherical Collapse in Chameleon Models

    Article, Preprint English OPEN
    Brax, Ph; Rosenfeld, R; Steer, D A; (2010)
    We study the gravitational collapse of an overdensity of nonrelativistic matter under the action of gravity and a chameleon scalar field. We show that the spherical collapse model is modified by the presence of a chameleon field. In particular, we find that even though ...
