Photoemission Discussion
Discussion Leader-Mike Norman (Argonne Natl. Lab.)
Z.-X. Shen (Stanford Univ.); Juan-Carlos Campuzano (Argonne Natl. Lab./Univ. Illinois); Peter Johnson (Brookhaven Natl. Lab.);Joe Orenstein (UC-Berkeley)

Nodal States: Are there quasiparticles or not? What is the relation of ARPES lineshapes to ab transport scattering rates? Is there evidence for stripes? What is the origin of the velocity kink along the nodal direction?

Antinodal States: Do the spectral peaks disappear or broaden with temperature? Is their weight related to the superfluid density? Are their linewidths related to the 41 meV resonance?

Fermi surfaces: Are they electron-like or hole-like? Should we use a conventional picture, or one based on stripes? Is there a connection of the metallic dispersion to that of the insulator?
