| Popis: | We investigate the interaction between a heavy quark-antiquark pair in color octet configuration in gluon plasma. We calculate nonperturbatively an effective thermal potential for such a pair through the study of the correlation function of a hybrid state with $Q \bar{Q}$ octet and an adjoint gluon source in the static limit. We discuss the extraction of an octet potential, and present results for the effective thermal potential between octet $Q \bar{Q}$ pair in gluon plasma for moderately high temperatures $\lesssim 2 T_c$. The implications of our result are discussed. Comment: 17 pages, 13 figures. Figures 8, 9 and two figures in appendix modified. Some minor notational changes. No change of conclusion |
