Metastable Supersymmetry Breaking in a Cooling Universe
Vadim S. Kaplunovsky
TL;DR
This paper explores how the early Universe's cooling process favors metastable supersymmetry-breaking vacua over stable ones, using the ISS model as a case study to understand cosmological implications for SUSY breaking.
Contribution
It provides a cosmological perspective on metastable SUSY breaking, demonstrating that early Universe cooling naturally favors metastable vacua, with analysis based on the ISS model.
Findings
Cooling Universe favors metastable SUSY vacua
Analysis of the ISS model supports the cosmological preference
Metastable SUSY breaking is plausible in early cosmology
Abstract
I put metastable supersymmetry breaking in a cosmological context. I argue that under reasonable assumptions, the cooling down early Universe favors metastable SUSY-breaking vacua over the stable supersymmetric vacua. To illustrate the general argument, I analyze the early-Universe history of the Intriligator-Seiberg-Shih model.
