Remarks on branes, fluxes, and soft SUSY breaking
Albion Lawrence, John McGreevy
TL;DR
This paper reviews how soft SUSY-breaking terms are realized in local type II string models with branes and fluxes, and introduces a new perspective on D-brane configurations and their relation to FI terms in Calabi-Yau backgrounds.
Contribution
It provides a new observation linking D-brane configuration space to nonperturbative hypermultiplet vevs and FI terms in Calabi-Yau backgrounds.
Findings
Identification of vevs for nonperturbative charged hypermultiplets with FI terms
New insight into D-brane configuration space in Calabi-Yau backgrounds
Review of soft SUSY-breaking terms in local type II models
Abstract
We review recent work identifying soft SUSY-breaking terms in local type II string models with branes and magnetic fluxes. We then make a new observation about the configuration space of D-branes in Calabi-Yau backgrounds, and identify vevs for nonperturbative charged hypermultiplets in Calabi-Yau backgrounds with N=2 Fayet-Iliopoulos terms.
