Non-minimal Split Supersymmetry
We present an extension of the minimal split supersymmetry model, which is capable of explaining the baryon asymmetry of the Universe. Instead of MSSM we start from NMSSM and split its spectrum in such a way that the low energy theory contains neutral particles, in addition to the content of minimal split supersymmetry. They trigger the strongly first order electroweak phase transition (EWPT) a...

متن کاملSplit extended supersymmetry
We show how splitting supersymmetry reconciles a class of intersecting brane models with unification. The gauge sector in these models arises in multiplets of extended supersymmetry while matter states are in N = 1 representations. A deformation of the angles between the branes gives large masses to squarks and sleptons, as well as supersymmetry breaking contributions to other string states. Th...
متن کاملGluino Decays in Split Supersymmetry
We compute the gluino lifetime and branching ratios in Split Supersymmetry. Using an effective–theory approach, we resum the large logarithmic corrections controlled by the strong gauge coupling and the top Yukawa coupling. We find that the resummation of the radiative corrections has a sizeable numerical impact on the gluino decay width and branching ratios. Finally, we discuss the gluino deca...
متن کاملSome Comments on “Split” Supersymmetry
An argument against tolerating finetuning in the Higgs sector is presented, by emphasizing the difference between (well understood) quantum corrections to scalar masses and the (unsolved) problem of the cosmological constant. I also point out that “split” supersymmetry, where all scalars except one Higgs boson have masses many orders of magnitude above the weak scale, is not compatible with sim...
