Thanks for the ping. I think cSinha has the best theory of superconductivity.

The Fermion-Lochon model and the pseudogap in cuprate superconductors
Sinha, KP (1999) The Fermion-Lochon model and the pseudogap in cuprate superconductors. In: 1999 University of Miami Conference on High Temperature Superconductivity, 7-13 Jan. 1999, Coral Gables, FL, USA, pp. 122-125.

Abstract
The interaction mechanism involving fermions and lochons (local charged bosons) located at polarizable dielectric regions in the layered cuprate systems is discussed in the context of the pairing symmetry, the appearance of the resonance peak and the pseudogap which is seen above . It is found that the mechanism allows both s and d waves and the dominance of one or the other depends on the relative values of the Fermi energy and the nearest neighbor hopping integral. The model accounts for the pseudogap and the resonance peak is identified with the local pair fluctuation state. The mechanism, along with a weak phonon contribution, emerges as an acceptable model for NTSC

Abstract
The mechanism involving phonons and lochons (local charged bosons, local pairs) developed earlier for cuprate superconductors is applied for the study of the gap anisotropy in these systems. It is found that besides intraplanar pairing the lochon-induced interlayer pairing gives rise to an anisotropic s-wave gap which is capable of changing sign in some regions on the Fermi surface.
