Rhic Physics and Beyond: Kay Kay Gee Day

This is a proceedings from a memorial workshop in honor of Klaus Kinder-Geiger, or "Kay Kay Gee". The workshop covered a variety of topics of current interest for the collisions of large nuclei at very high energies. This includes whether a quark-gluon plasma is produced in such collisions, and possible signals, such as through J/Psi production, Hanbury-Brown-Twiss interferometry of pions, and the shape of the pion spectra at high transverse momentum. Cascade models, especially the parton cascade models developed by Klaus, were discussed at length.
