Speaker: Vigilante Di Risi, PhD student at Federico II University of Naples. In his talk, Vigilante will tell us about QCD and dual theories. More on this below.
Abstract: In the late nineties, in a series of exceptional papers, Seiberg provided strong support for the existence of a consistent picture of an electric-magnetic duality within a supersymmetric framework. One of the most relevant of Seiberg鈥檚 results has been the identification of the boundary of the conformal window for supersymmetric QCD as function of the number of flavours and colours. Generalizing Seiberg's ideas to non-supersymmetric QCD it is possible to recover analytical results on the extension of the QCD conformal window. By means of 't Hooft anomaly matching, magnetic duals of QCD can be built and some aspects of the QCD non-perturbative regime can be trustably discussed. The agreement with analogous computations (e.g. lattice QCD, all-orders beta function, ladder approximation) has been shown to be excellent.
