After an introduction recalling the theoretical motivation for low energy (100GeV to TeV
scale) supersymmetry, this review describes the theory and experimental implications of the …

The existence of dark matter provides strong evidence for physics beyond the standard
model. Extending the standard model with the Peccei–Quinn symmetry and/or …

We explore some fundamental differences in the phenomenology, cosmology and model
building of Split Supersymmetry compared with traditional low-scale supersymmetry. We …

We evaluate the gravitino production rate in supersymmetric QCD at high temperature to
leading order in the gauge coupling. The result, which is obtained by using the resummed …

A bstract In this paper, we incorporate the modular S 4 flavor symmetry into the
supersymmetric version of the minimal type-I seesaw model, in which only two right-handed …

Cosmological issues are examined when the gravitino is the lightest superparticle (LSP) and
R-parity is broken. Decays of the next lightest superparticles occur rapidly via R-parity …

We investigate supergravity models in which the lightest supersymmetric particle (LSP) is a
stable gravitino. We assume that the next-lightest supersymmetric particle (NLSP) freezes …

Considering gravitino dark matter scenarios, we study constraints on the reheating
temperature of inflation. We present the gauge-invariant result for the thermally produced …

We investigate in detail leptogenesis by the decay of a coherent right-handed sneutrino Ñ
having dominated the energy density of the early universe, which was originally proposed …

We consider the possibility that the gravitino might be the lightest supersymmetric particle
(LSP) in the constrained minimal extension of the Standard Model (CMSSM). In this case …
