N2 - We argue that recently measured downward dispersion of the neutron resonance peak in cuprate superconductors is naturally explained if the resonance is viewed as a spin-1 collective mode in a d− wave superconductor. The reduction of the resonant frequency away from the antiferromagnetic wave vector is a direct consequence of the momentum dependence of the d− wave superconducting gap. When the magnetic correlation length becomes large, the dispersion should become magnonlike, i.e., curve upwards from (π, π).
