“…This differs from the original split SUSY construction [37][38][39] where the μ term and thus the Higgsinos had mass of order the gaugino masses. In this model, all the parameters in the Higgs potential are Oðm 3=2 Þ, and among them one tuning is required to get the Higgs vacuum expectation value (VEV) and the mass of the lightest physical scalar to be of order the weak scale.…”

“…On the other hand, the flavor observables that constrain the flavor breaking in the sfermion sector correspond to higher dimension operators, so they decouple quickly with heavier sfermion masses. Therefore, spectra where the sfermions are much above the weak scale such as split [37][38][39] and supersplit [2,40,41] supersymmetry can be used for radiative flavor generation with sfermions potentially as heavy as the GUT or Planck scale [31].…”

Split supersymmetry radiates flavor

Radiative flavor models where the hierarchies of Standard Model (SM) fermion masses and mixings are explained via loop corrections are elegant ways to solve the SM flavor puzzle. Here we build such a model in the context of mini-split supersymmetry (SUSY) where both flavor and SUSY breaking occur at a scale of 1000 TeV. This model is consistent with the observed Higgs mass, unification, and dark matter as a weakly interacting massive particle. The high scale allows large flavor mixing among the sfermions, which provides part of the mechanism for radiative flavor generation. In the deep UV, all flavors are treated democratically, but at the SUSY-breaking scale, the third, second, and first generation Yukawa couplings are generated at tree level, one loop, and two loops, respectively. Save for one, all the dimensionless parameters in the theory are Oð1Þ, with the exception being a modest and technically natural tuning that explains both the smallness of the bottom Yukawa coupling and the largeness of the Cabibbo angle.

“…Split supersymmetry (split-SUSY) [1][2][3] for example, gives up the explanation of the hierarchy problem while keeping the other main virtue of the minimal supersymmetric standard model: the connection between gauge coupling unification (GCU) and viable dark matter (DM) candidates without the imposition of any ad hoc discrete symmetry. In fact, the discrete symmetry required to avoid fast proton decay in supersymmetry can be embedded in an anomaly-free gauge symmetry (see for instance [4][5][6][7][8]) in order to avoid quantum gravitational effects which would violate it [9][10][11].…”

Fermion dark matter from SO(10) GUTs

We construct and analyze nonsupersymmetric SO(10) standard model extensions which explain dark matter (DM) through the fermionic Higgs portal. In these SO(10)-based models the DM particle is naturally stable since a Z 2 discrete symmetry, the matter parity, is left at the end of the symmetry breaking chain to the standard model. Potentially realistic models contain the 10 and 45 fermionic representations from which a neutralino-like mass matrix with arbitrary mixings can be obtained. Two different SO(10) breaking chains will be analyzed in light of gauge coupling unification: the standard path SU(5) × U (1) X and the left-right symmetry intermediate chain.The former opens the possibility of a split supersymmetric-like spectrum with an additional (inert) scalar doublet, while the later requires additional exotic scalar representations associated to the breaking of the left-right symmetry.

“…Assuming a large soft-breaking scale for all MSSM scalars [26,27,28,29,30] pushes squarks, sfermions and heavy Higgses out of the reach of the LHC without affecting the gaugino sector. Even though the hierarchy problem will not be solved without an additional logarithmic fine tuning in the Higgs sector, such models can be constructed to provide a good dark-matter candidate and realize grand unification while minimizing proton decay and FCNCs.…”

This collection of studies on new physics at the LHC constitutes the report of the supersymmetry working group at the Workshop 'Physics at TeV Colliders', Les Houches, France, 2007. They cover the wide spectrum of phenomenology in the LHC era, from alternative models and signatures to the extraction of relevant observables, the study of the MSSM parameter space and finally to the interplay of LHC observations with additional data expected on a similar time scale. The special feature of this collection is that while not each of the studies is explicitely performed together by theoretical and experimental LHC physicists, all of them were inspired by and discussed in this particular environment.2
