Model
NLSUSY GR theory has been constructed by the geometrical arguments on new space-time just inspired by NLSUSY. NLSUSY GR equipped with space-time origin spontaneous SUSY breaking produces the fundamental action(SGM action) in ordinary Riemann space-time, i.e. the Einstein Gravity, Nambu-Goldstone fermions and the cosmological term. The vacuum of SGM action is realised when NG frmions...

Model
A large class of non-minimal gauge mediation models, such as (semi-)direct gauge mediation, predict a hierarchy between the masses of the supersymmetric standard model gauginos and those of scalar particles. In addition, the GUT relation of the gaugino masses is broken unlike the case of minimal gauge mediation. I discuss the LHC signals and cosmology of such models.

Model
We consider an extension of the minimal supersymmetric
standard model (MSSM) with extra U(1)_B × U(1)_L
gauge symmetry that are broken spontaneously.
Salient features of this model are that there are two different
types of cold dark matter candidates, and neutral scalar sector
has a rich structure. One can accommodate the neutrino
masses and mixings. There could be interesting...

Model
Vacuum stability bounds on flavor-violating trilinear soft terms are revisited from the viewpoint that one should not rule out parameter space that leads to a metastable standard vacuum if it is sufficiently long-lived. Bounds are obtained by numerical computation of false vacuum decay rate. Implications are discussed on future searches for FCNC processes.

Model
We study SUSY breaking and its transmission to the supersymmetric Standard Model in models with anomalous U(1) gauge symmetry where non-perturbative Polonyi term stabilizes the Green-Schwarz modulus. The pattern of SUSY breaking crucially relies on the ratio R between the Fayet-Iliopoulos term and the mass contribution of the Green-Schwarz modulus to the anomalous gauge boson. In the presence...

Model
We investigate renormalization effects on the low energy mass spectrum of the minimal supersymmetric standard model (MSSM), using a calculable model of spontaneous supersymmetry breaking in the hidden sector. We model the hidden sector by N=2 supersymmetric quantum chromodynamics with gauge group SU(2)xU(1) and N_f=2 matter hypermultiplets, perturbed by a Fayet-Iliopoulos term which breaks the...
