Abstract: | We discuss the spectrum of open string and point particle excitations in QCD with various source representations. Some general relations are introduced and lattice results presented. In particular, we discuss the short-distance behaviour, relate this to perturbation theory expectations and comment on the matching between low-energy matrix elements and high-energy Wilson coefficients, within the framework of effective field theories. |
