Bootstrapping pions at large N. Part II. Background gauge fields and the chiral anomaly

Abstract We continue the program [1] of carving out the space of large N confining gauge theories by modern S-matrix bootstrap methods, with the ultimate goal of cornering large N QCD. In this paper, we focus on the effective field theory of massless pions coupled to background electromagnetic field...
