The Complete One-Loop Dilation Operator of N=2 SuperConformal QCD
Abstract
We evaluate the full planar one-loop dilation operator of N=2 SuperConformal QCD, the SU(Nc) super Yang-Mills theory with Nf = 2 Nc fundamental hypermultiplets, in the flavor-singlet sector. Remarkably, the spin-chain Hamiltonian turns out to be completely fixed by superconformal symmetry, as in N=4 SYM. We present a more general calculation, for the superconformal quiver theory with SU(Nc)X SU(Nc) gauge group, which interpolates between N=2 SCQCD and the Z2 orbifold of N=4 SYM; here symmetry fixes the Hamiltonian up to a single parameter, corresponding to the ratio of the two marginal gauge couplings.
