Quantitative Tests of Color Evaporation: Charmonium Production

Abstract
The color evaporation model simply states that charmonium production is described by the same dynamics as production, {\em i.e.}, by the formation of a colored pair. Its color happens to be bleached by soft final-state interactions. We show that the model gives a complete picture of charmonium production including low-energy production by proton, photon and antiproton beams, and high-energy production at the Tevatron and HERA. Our analysis includes the first next-to-leading-order calculation in the color evaporation model.
