Within the framework of the Charge Density Wave Quantum Critical Point (CDW
-QCP) scenario for high-T-c superconductors (HTCS) we introduce a model for
tight-binding electrons coupled to quasi-critical fluctuations. In the nor
mal state our model reproduces features the Fermi Surface (FS) observed in
ARPES measurements on optimality doped Bi2212, such as the anisotropic supp
ression of spectral weight around the M points of the Brillouin zone. The s
pectral density is characterized by a transfer of spectral weight from the
main quasiparticle peak to dispersing shadow peaks which originate branches
of a shadow FS. In the superconducting state our model reproduces the d-wa
ve symmetry of the gap parameter, which results from a balance between smal
l-q attraction and large-q repulsion. The gap parameter is enhanced due to
cooperative effects of charge and spin fluctuations.
