概要
Supersymmetry breaking mechanism plays one of the most important roles for constructing realistic models within supersymmetric theory. Either F-term or D-term breaking scenarios have been studied in most phenomenological models. What else is available? In this talk, I will discuss a new possibility, which I call aether SUSY breaking, where some part of Poincare symmetry is also broken simultaneously. I will show a concrete model of the new scenario and discuss SUSY breaking mediation to matter sectors. It turns out that SUSY breaking can be mediated to matters in a very similar way to the gravity mediation in F-term models. I will also discuss cosmological constraints on the model, which gives the upper bound on the SUSY breaking scale (
