Cosmological tracking solution and the Super-Higgs mechanism
Ricardo C. G. Landim
TL;DR
This paper proposes a model linking the Super-Higgs mechanism in supergravity to cosmological tracking solutions, which naturally explains late-time cosmic acceleration and addresses the coincidence problem.
Contribution
It introduces a minimal supergravity framework with a specific superpotential that connects supersymmetry breaking to cosmological evolution.
Findings
The model predicts late-time accelerated expansion.
It provides a potential solution to the coincidence problem.
The approach unifies supersymmetry breaking with cosmological dynamics.
Abstract
In this paper we argue that minimal supergravity with flat K\"ahler metric and a power-law superpotential can relate the Super-Higgs mechanism for the local spontaneous supersymmetry breaking and the cosmological tracking solution, leading in turn to a late-time accelerated expansion of the universe and alleviating the coincidence problem.
