Abstract
We present a model of charmonium as two heavy quarks propagating classically in a weakly coupled quark-gluon plasma. The quarks interact via a static, color-dependent potential and also suffer collisions with the plasma particles. We calculate the radiation width of the color octet state (for fixed, classical qq¯ separation) and find that the state is long lived provided a finite gluon mass is used to establish a threshold energy.
