Upsilon Dissociation in Quark-Gluon Plasma

Abstract

I consider the dissociation of the upsilon meson due to absorption of a thermal gluon. I discuss the dissociation rate in terms of the energy density, the number density, and the temperature of the quark-gluon plasma. I compare this to the effect due to screening.

Comments: 5 pages, added calculations on screening; added figure
