چکیده

We show that for gaugino mediated supersymmetry breaking the gravitino mass is bounded from below. For a size of the compact dimensions of order the unification scale and a cutoff given by the higher-dimensional Planck mass, we find m3/2 & 10GeV. In a large domain of parameter space, the gravitino is the lightest superparticle with a scalar τ̃ -lepton as the next-to-lightest superparticle.

The Gravitino-Stau Scenario after Catalyzed BBN

We consider the impact of Catalyzed Big Bang Nucleosynthesis on theories with a gravitino LSP and a charged slepton NLSP. In models where the gravitino to gaugino mass ratio is bounded from below, we derive a lower bound on the gaugino mass parameter m1/2. As a concrete example, we determine the parameter space of gaugino mediation that is compatible with all cosmological constraints. Email: jk...

Retrofitted Gravity Mediation without the Gravitino-overproduction Problem

We propose a retrofitted gravity mediation model which alleviates the gravitino overproduction from decays of an inflaton and a supersymmetry breaking field. In the model, we introduce an approximate U(1) symmetry under which the supersymmetry breaking field is charged, although it is broken by a mass term of messenger fields to generate gaugino masses of order the weak scale. In a low-scale in...

Dark Matter from Gaugino Mediation

We study dark matter for gaugino-mediated supersymmetry breaking and compact dimensions of order the grand unification scale. Higgs fields are bulk fields, and in general their masses differ from those of squarks and sleptons at the unification scale. As a consequence, at different points in parameter space, the gravitino, a neutralino or a scalar lepton can be the lightest (LSP) or next-to-lig...

A Bottom - Up Approach to Moduli Dynamics in Heavy Gravitino Scenario : Superpotential , Soft Terms and Sparticle Mass Spectrum

Physics of moduli fields is examined in the scenario where gravitino is relatively heavy with mass of order 10 TeV, which may be favored in view of the severe gravitino problem. The form of moduli superpotential is shown to be determined, if one imposes a phenomenological requirement that no physical CP phase arises in gaugino masses from conformal anomaly mediation. This bottom-up approach all...

More Visible Effects of the Hidden Sector

There is a growing appreciation that hidden sector dynamics may affect the supersymmetry breaking parameters in the visible sector (supersymmetric standard model), especially when the dynamics is strong and superconformal. We point out that there are effects that have not been previously discussed in the literature. For example, the gaugino masses are suppressed relative to the gravitino mass. ...
