Abstract
We have performed calculations of the response function for electronic Raman scattering in clean d-wave superconductors including vertex corrections in a conserving approximation and obtain contributions to the B1g Raman response that we believe have not been considered previously. These contributions remove the well-known singularity at the threshold energy 2Δ0 for a d-wave superconductor, yielding instead a peak at a slightly higher frequency with an intensity of the same order as the A1g response. Our results are in good agreement with experimental data on YBa2Cu3O7.
