| Description | Speaker: Quentin Bonnefoy Title: Positivity bounds on nonlinear supersymmetry Room: 3024 Host: Da Liu Abstract: Effective theories of spontaneously broken supersymmetry (SUSY) couple Goldstinos and matter fields. A convenient formalism, that of constrained superfields, recycles the techniques used to build theories with unbroken SUSY. However, the associated constraints are not unique. Using positivity bounds, I will argue that the use of some of those constraints is forbidden by the requirement that there should exist a UV completion. I will also illustrate how this is captured by explicit matching computations. These results resonate with causality issues caused by gravitinos during inflation. |
