Lagrangian for a Non-Lagrangian Field Theory with N=2 Supersymmetry

We suggest that at least some of the strongly coupled N = 2 quantum field theories in 4D can have a nonconformal N = 1 Lagrangian description flowing to them at low energies. In particular, we construct such a description for the N = 2 rank one superconformal field theory with E-6 flavor symmetry, for which a Lagrangian description was previously unavailable. We utilize this description to compute several supersymmetric partition functions.
