Correlators of the global symmetry currents of 4D and 6D superconformal theories Original Research Article

We study the two-point correlators of the currents of the E8 global symmetry in the N = (1, 0) superconformal six-dimensional theory as well as in the 4D superconformal theories upon toroidal compactification. From the high-energy behavior of the correlator we deduce that in 4D 10 copies of the superconformal theory with E8 global symmetry can be coupled to an N = 2 E8 gauge theory. We present three alternative derivations for the expression for the correlators. One from field theory, one from M-theory and one from F-theory.
