Supersymmetric Large Extra Dimensions
C.P. Burgess
TL;DR
This paper discusses a supersymmetric large extra dimensions framework that aims to solve the cosmological constant problem by introducing a relaxation mechanism to keep vacuum energy contributions small, with potential observational implications.
Contribution
It introduces a novel supersymmetric large extra dimensions model that addresses the cosmological constant problem through a unique relaxation mechanism.
Findings
The relaxation mechanism can suppress vacuum energy contributions from low-energy particles.
Preliminary discussions suggest observable consequences of the model.
The framework offers a new approach to the cosmological constant problem.
Abstract
This article summarizes the proposal to address the cosmological constant problem within the framework of supersymmetric large extra dimensions (SLED). The proposed mechanism is described, emphasizing the relaxation mechanism which ensures that low-energy particles like the electron do not contribute too large a vacuum energy. This is followed by a preliminary discussion of outstanding issues and observational consequences.
