摘要：

We evaluate the full planar one-loop dilation operator of N = 2 SuperConformal QCD, the SU(N-c) super Yang-Mills theory with N-f = 2N(c) 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(N-c) x SU(N-c) gauge group, which interpolates between N = 2 SCQCD and the Z(2) 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.
