Abstract

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 QQˉQ \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 QQˉQ \bar{Q} pair in gluon plasma for moderately high temperatures 2Tc\lesssim 2 T_c. The implications of our result are discussed.
