Quantum Seiberg-Witten periods for N=2 SU(Nc) SQCD around the superconformal point

Abstract

We study the quantum Seiberg-Witten periods of N=2 superconformal field theories which are obtained by taking the scaling limit of N=2 SU(Nc) SQCD around the superconformal fixed point. The quantum Seiberg-Witten curves of these superconformal field theories are shown to be classified into the Schrödinger type and the SQCD type, which depend on flavor symmetry at the fixed point. We study the quantum periods and compute the differential operators which relate the quantum periods to the classical ones up to the fourth-order in the deformation parameter.
