Description
I consider a non-common type of 4D/2D correspondence, which allows to compute the confining spectrum of 4D supersymmetric QCD by means of 2D superconformal world-sheet theory, corresponding to N=2 supersymmetric version of 2D black hole. Amazingly enough, both Kahler and complex deformations of the world-sheet theory affect only the number of states in 4D. The conjecture survives under few tests on state's counting, reduced on field theory side to certain exercises in representation theory.
