On exact correlation functions in SU(N) N = 2 $$ \mathcal{N}=2 $$ superconformal QCD
On exact correlation functions in SU(N) N = 2 $$ \mathcal{N}=2 $$ superconformal QCD
We consider the exact coupling constant dependence of extremal correlation functions of $$ \mathcal{N}=2 $$ chiral primary operators in 4d $$ \mathcal{N}=2 $$ superconformal gauge theories with gauge group SU(N) and N f = 2N massless fundamental hypermultiplets. The 2- and 3-point functions, viewed as functions of the exactly marginal …
