1. Static quarks in finite temperature lattice QCD Péter Petreczky
Physics Department and RIKEN-BNL Research Center
Motivation : the study and interpretation of static meson correlators is much more
easier than the analysis of heavy meson correlators ( see talk by T. Umeda )
provide useful non-perturbative input into pNRQCD at T>0
( see talk by A. Vairo )

11. Summary
The lattice study of the T-dependence of spatial correlators of static
quark anti-quark pair shows that singlet and adjoint states are the relevant degrees of
freedom at short distances
The T-dependence of the correlators does not depend on the details of the operators:
the singlet correlators show little T-dependence at short distances, while
adjoint correlators show significant T-dependence corresponding to melting of hybrid
states at the deconfinement transition.
Perturbaton theory can describe many features of static quark anti-quark correlators
at high temperatures .
