| dc.description | In split supersymmetry, the supersymmetric scalar particles are all very heavy, at least at the order of 10^9 GeV, but the gauginos, Higgsinos, and one of the neutral Higgs bosons remain below a TeV. Here we further split the split supersymmetry by taking the Higgsino mass parameter μto be very large. In this case, the μproblem is avoided and we keep the wino as a dark matter candidate. A crude gauge coupling unification is still preserved. Dark matter signals and collider phenomenology are discussed in this μ-split SUSY scenario. The most interesting dark matter signal is the annihilation into monochromatic photons. In colliders, chargino-pair and the associated chargino-neutralino production cross sections have a certain ratio due to gauge couplings, and the chargino has long decays. | |
