R - invariant New Inflation Model vs Supersymmetric Standard Model
We revisit the implications of the R-invariant New Inflation model to the supersymmetric standard model in light of recent discussion of gravitino production processes by the decay of the inflaton or the supersymmetry breaking field. We show that the models with supergravity mediation do not go well with the R-invariant New Inflation model, where the gravitino abundance produced by the decay of...
متن کاملR-Parity Violating Minimal Supersymmetric Standard Model
We show that the present experimental limits on electron-nucleon interactions that violate both parity and time reversal invariance provide new stringent bounds on the imaginary parts of some of the products of the R-parity violating coupling constants in the R-parity violating Minimal Supersymmetric Standard Model. 11.30.Er,12.60.Jv,32.10.Dk Typeset using REVTEX
متن کاملSupersymmetric topological inflation model
We propose a topological inflation model in supergravity. In this model, the vacuum expectation value (VEV) of a scalar field takes a value much larger than the gravitational scale MG ≃ 2.4 × 10 GeV, which is large enough to cause topological inflation. On the other hand, expansions of the Kähler potential and the superpotential beyond the gravitational scale are validated by the introduction o...
متن کاملA Supersymmetric Standard Model of Inflation with Extra Dimensions
We embed the supersymmetric standard model of hybrid inflation based on the next-tominimal superpotential term λNHuHd supplemented by an inflaton term κφN2, into an extra-dimensional framework, in which all the Higgs fields and singlets live in the bulk, while all the matter fields live on the brane. All the parameters of the effective 4d model can then be naturally understood in terms of a fun...
متن کاملGauge-invariant inflaton in the minimal supersymmetric standard model.
We argue that all the necessary ingredients for successful inflation are present in the flat directions of the Minimally Supersymmetric Standard Model. We show that out of many gauge-invariant combinations of squarks, sleptons, and Higgs bosons, there are two directions, LLe and udd, which are promising candidates for the inflaton. The model predicts more than 10(3) e-foldings, with an inflatio...
