Supersymmetric classical cosmology
Abstract
In this work a supersymmetric cosmological model is analyzed in which we consider a general superfield action of a homogeneous scalar field supermultiplet interacting with the scale factor in a supersymmetric FRW model. There appear fermionic superpartners associated with both the scale factor and the scalar field, and classical equations of motion are obtained from the superWheelerDeWitt equation through the usual WKB method. The resulting supersymmetric EinsteinKleinGordon equations contain extra radiation and stiff matter terms, and we study their solutions in flat space for different scalar field potentials. The solutions are compared to the standard case, in particular those corresponding to the exponential potential, and their implications for the dynamics of the early Universe are discussed in turn.

We present an N = 1 locally supersymmetric theory in which all constraints for a successful new inflationaryuniverse scenario are satisfied and the gravitino mass is on the order of the electroweak scale. Sufficient baryon asymmetry is generated and the overproduction of entropy due to gravitinos and/or coherent field oscillations (which is typical of supersymmetric models) is avoided.

Cosmology of supersymmetric models with lowenergy gauge mediation
We study the cosmology of supersymmetric models in which the supersymmetrybreaking effects are mediated by gauge interactions at about the 10{sup 5} GeV scale. We first point out that the gravitino is likely to overclose the Universe in this class of models. This requires an entropy production, which prefers a baryogenesis mechanism at a relatively low temperature. The AffleckDine mechanism for baryogenesis is one of the possibilities to generate enough baryon asymmetry, but the analysis is nontrivial since the shape of the potential for the flat direction differs substantially from the conventional hidden sector case. To see this, we firstmore » 
Colliders as a simultaneous probe of supersymmetric dark matter and Terascale cosmology
Terascale supersymmetry has the potential to provide a natural explanation of the dominant dark matter component of the standard {Lambda}CDM cosmology. However once we impose the constraints on minimal supersymmetry parameters from current particle physics data, a satisfactory dark matter abundance is no longer prima facie natural. This Neutralino Tuning Problem could be a hint of nonstandard cosmology during and/or after the Terascale era. To quantify this possibility, we introduce an alternative cosmological benchmark based upon a simple model of quintessential inflation. This benchmark has no free parameters, so for a given supersymmetry model it allows an unambiguous prediction ofmore » 
Supersymmetric grand unified theories and cosmology
By examining the behavior of supersymmetric grand unified theories (GUT's) in the very early universe we find two classes of realistic models. In one of them supersymmetry is broken at or near superheavy GUT scale. The cosmological implications of such models are expected to be similar to those of nonsupersymmetric GUT's. In the second class of models, the superheavy GUT scale is related to the supersymmetrybreaking scale in the manner of Witten. Two types of cosmological scenarios appear possible in this case, either with or without an intermediate (new) inflationary phase. They can be experimentally distinguished, since the former predictsmore » 
Locally supersymmetric cosmology and the gauge hierarchy
We motivate and present a locally supersymmetric theory that satisfies all the constraints for a successful, new inflationaryuniverse scenario, and has a naturally light gravitino. The reheating temperature is sufficiently high to explain the observed baryon asymmetry.
