Cosmology and Models of Supersymmetry Breaking in String Theory

TL;DR

This paper discusses the cosmological evolution of the dilaton modulus in string theory, focusing on how supersymmetry breaking occurs when moduli fields settle into their vacuum states.

Contribution

It introduces recent ideas on the dynamics of the dilaton modulus during the early universe's evolution towards its vacuum expectation value.

Insights into the behavior of the dilaton field in cosmological contexts

Implications for supersymmetry breaking mechanisms in string theory

Potential effects on early universe cosmology

Abstract

Supersymmetry breaking in string theory is expected to occur when moduli fields acquire non-trivial expectation values. In the early universe these fields start out displaced from their final destinations. I present some recent ideas about the cosmological evolution of the dilaton modulus field on the way to its vacuum expectation value.
