This paper discusses the microscopic origins of supersymmetry breaking, exploring potential dynamics and their integration into string theory, aiming to connect low-energy phenomenology with fundamental high-energy theories.

Contribution

It provides an overview of recent progress in understanding supersymmetry breaking mechanisms and their embedding into string theory frameworks.

Findings

Improved understanding of supersymmetry breaking dynamics

Potential pathways to incorporate supersymmetry into string theory

Insights into low-energy manifestations of high-energy symmetries

Abstract

If supersymmetry turns out to be a symmetry of nature at low energies, the first order of business to measure the soft breaking parameters. But one will also want to understand the symmetry, and its breaking, more microscopically. Two aspects of this problem constitute the focus of these lectures. First, what sorts of dynamics might account for supersymmetry breaking, and its manifestation at low energies. Second, how might these features fit into string theory (or whatever might be the underlying theory in the ultraviolet). The last few years have seen a much improved understanding of the first set of questions, and at least a possible pathway to address the second.
