Determining the Fluctuations Responsible for the Singular
Fermi-Liquid and the Superconductivity in the Cuprates

I will report on Laser
based ARPES of unprecedented accuracy and stability
(taken by the group of Xingjiang Zhou, IOP, Beijing), together
with a method
of analysis (done with the group of Han-Yong Choi, Asia
Pacific Center for
Theoretical Physics, Korea), to quantitatively extract the
many-body effects
due the coupling of fermions to the fluctuation spectra in
both the full symmetry
(normal) and the d-wave sub-group (pairing) symmetry of the
lattice in a family
of cuprates.
