摘要：
We study soft supersymmetry breaking in local models of type II string theory compactifications with branes and fluxes. In such models, magnetic fluxes can be treated as auxiliary fields in N = 2 SUSY multiplets. These multiplets appear as "spurion superfields" in the low-energy effective action for the local model. We discuss the pattern of SUSY breaking from N = 2 to N = 1 to N = 0 in these models, and then identify the fields leading to soft SUSY breaking terms in various examples. In the final section, we reconsider arguments for the Dijkgraaf-Vafa conjecture in gauge theories with softly broken supersymmetry.
