A Comment on Technical Naturalness and the Cosmological Constant
Nissan Itzhaki
TL;DR
This paper introduces a dynamical relaxation model for the cosmological constant, linking its naturalness to bounds on supersymmetry breaking and reheating temperatures at the TeV scale.
Contribution
It presents a novel model that connects the naturalness of the cosmological constant to supersymmetry breaking and reheating constraints.
Findings
Upper bound on supersymmetry breaking scale
Reheating temperature constrained to TeV scale
Model supports dynamical relaxation of vacuum energy
Abstract
We propose a model of dynamical relaxation of the cosmological constant. Technical naturalness of the model and the present value of the vacuum energy density imply an upper bound on the supersymmetry breaking scale and the reheating temperature at the TeV scale.
