A proposal to determine the spectrum of pairing-glue in high- temperature superconductors
13 June 2003
We propose a method for an analysis of the angle-resolved photemission data in two-dimensional anisotropic superconductors which directly yields the spectal function of the bosons mediating Cooper pairing. The method includes a self-consistency check for the validity of the approximations made in the analysis. We explicitly describe the experimental data needed for implementing the proposed procedure.
