Abstract

We analyze the Raman-scattering response in a two-dimensional dx2−y2-wave superconductor and point out a strong suppression of relative intensity in the screened A1g channel compared to the B1g channel for a generic tight-binding model. This is in contrast with the observed behavior in high-Tc superconductors.
