Resummed Quantum Gravity Prediction for the Cosmological Constant and Constraints on SUSY GUTS

TL;DR

This paper employs a resummed quantum gravity approach within Planck scale cosmology to estimate the cosmological constant, providing constraints on supersymmetric GUT models based on the closeness of the estimate to experimental data.

Contribution

It introduces a novel application of resummed quantum gravity to estimate the cosmological constant and constrains SUSY GUT models accordingly.

Findings

Constraints on SUSY GUT models based on estimate

Consistency checks support the approach

Abstract

We use our resummed quantum gravity approach to Einstein's general theory of relativity in the context of the Planck scale cosmology formulation of Bonanno and Reuter to estimate the value of the cosmological constant as \rho_\Lambda =(0.0024 eV)^4. We show that the closeness of this estimate to experiment constrains susy GUT models. We also address various consistency checks on the calculation.
