Query: Charmonium Cross Sections and the QGP   In this short review we summarize experimental information and theoretical
results for the low-energy dissociation cross sections of charmonia by light
hadrons. These cross sections are required for the simulation of charmonium
absorption through collisions with comovers in heavy ion collisions, which
competes with quark-gluon plasma production as a charmonium-suppression
mechanism. If the cross sections are sufficiently large these dissociation
reactions may be misinterpreted as an effect of quark-gluon plasma production.
Theoretical predictions for these RHIC-related processes have used various
methods, including a color-dipole scattering model, meson exchange models,
constituent interchange models and QCD sum rules. As the results have been
largely unconstrained by experiment, some of the predictions differ by orders
of magnitude, notably in the near-threshold regime that is most relevant to QGP
searches.
