摘要：

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 mu to be very large. In this case, the mu problem 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 mu-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.
