    Cosmology and astroparticles, dark matter searches
    The possible existence of a new light vector boson mediator of a gauge interaction under which SM particles are neutral and which couples with the SM via a kinetic mixing mechanism has recently been postulated by several authors. Such particle can be produced in e+e- collisions and/or decays of vector bosons and be visible in existing experiments, provided that the mixing parameter is of...

  2. 77. Searches for hidden valley particles with D0 detector in ppbar collisions at Fermilab

    Cosmology and astroparticles, dark matter searches
    In hidden valley scenarios, new particles with relatively light masses are hypothesized to exist in a "potential valley" separated from the standard model by a high potential barrier. At high energy colliders, this barrier could be crossed leading to the production of hidden valley particles which could decay to standard model particles after moderately short lifetimes. Results from...

  3. 118. Hidden valley searches in ATLAS

    Cosmology and astroparticles, dark matter searches
    A number of extensions of the Standard Model result in neutral and weakly-coupled particles that decay to multi hadrons or multi leptons with macroscopic decay lengths. These particles with decay paths that can be comparable with ATLAS detector dimensions represent, from an experimental point of view, a challenge both for the trigger and for the reconstruction capabilities of the ATLAS...

  4. 69. Searches for Supersymmetry with the CMS detector at the LHC
    Dr Edmund Widl (HEPHY)

    Cosmology and astroparticles, dark matter searches
    Supersymmetry may give rise to striking events that could be discovered early in LHC running. We discuss search strategies based on the generic event signatures of high jet multiplicity and large missing transverse momentum, optionally including leptons and photons in the final state. An important aspect of such searches is the commissioning of search variables with LHC data, and demonstrating...
