Sasmita Mishra, Wei Xue, Robert Brandenberger, Urjit Yajnik (McGill, and IIT Bombay)
TL;DR
This paper explores how gaugino condensation in string gas cosmology simultaneously stabilizes the dilaton and breaks supersymmetry, analyzing the resulting constraints on the supersymmetry breaking scale.
Contribution
It demonstrates that gaugino condensates used for dilaton stabilization inherently cause supersymmetry breaking in string gas cosmology.
Findings
Gaugino condensation breaks supersymmetry in this framework.
The mechanism constrains the scale of supersymmetry breaking.
Dilaton stabilization and supersymmetry breaking are interconnected.
Abstract
In this Note we study supersymmetry breaking via gaugino condensation in string gas cosmology. We show that the same gaugino condensate which is introduced to stabilize the dilaton breaks supersymmetry. We study the constraints on the scale of supersymmetry breaking which this mechanism leads to.
