Effective QCD Partition Function in Sectors with Non-Zero Topological Charge and Itzykson-Zuber Type Integral
Toshinao Akuzawa, Miki Wadati
Abstract
It was conjectured by Jackson et.al. that the finite volume effective partition function of QCD with the topological charge M-N coincides with the Itzyskon-Zuber type integral for M× N rectangular matrices. In the present article we give a proof of this conjecture, in which the original Itzykson-Zuber integral is utilized.
