Abstract:
Integrability is an intrinsically 2-dimensional tool which, perhaps surprisingly, has provided many useful predictions in larger dimensionalities as well by virtue of the 't Hooft expansion and string theory. As of today, most of the success in that direction has revolved around maximally supersymmetric examples such as N=4 SYM. We shall discuss a recently proposed set of models which remain integrable and simple even when all supersymmetries have been broken. Despite these models have some well-known pathologies (such as a lack of unitarity), I will argue that they are unexpectedly well-behaved and still convey information about physically interesting theories, such as N=4  SYM.
