at: 14:00 room 610  abstract: We will introduce a large class of N=1 superconformal theories Sk which is obtained from Gaiottoâ€™s N=2 class S via orbifolding. We will study the Coulomb branch of the theories in the class by constructing and analyzing their spectral curves. Using our experience from the N=2 AGT correspondence we will search for a 2D/4D relations (AGTk) for the N=1 theories of class Sk. From the curves we will identify the 2D CFT symmetry algebra and its representations, namely the conformal blocks of the Virasoro/Walgebra, that underlie the 2D theory and reproduce the SeibergWitten curves of the N = 1 gauge theories. We find that the blocks corresponding to the SU(N) Sk gauge theories involve fields in certain nonunitary representations of the WkN algebra. These conformal blocks give a prediction for the instanton partition functions of the 4D N = 1 SCFTs of class Sk.

Triangular Seminar Elli Pomoni (Humboldt)
at: 17:00 room K1.28  abstract: N = 2 SuperConformal QCD is perhaps the simplest theory outside the N = 4 "universality class" that we can attempt to study holographically. It is moreover continuously connected to the N = 4 class by an interpolating family of N = 2 SCFT. Careful analysis of its chiral spectrum points towards a gravity dual description via a noncritical string background. We then turn to the study of spin chains. The complete oneloop Hamiltonian and some higherloop results already reveal a rich dynamics. We present past results and current progress.
