The string spectrum from large Wilson loops

Abstract
We look at energies of the low lying states of the hadronic string in three dimensional SU(2) lattice gauge theory by forming correlation matrices among different sources. We are able to go to previously inaccessible time separations. This is made possible by using a new algorithm proposed by Lüscher and Weisz which lets us measure the exponentially small values of large Wilson loops with sufficient accuracy.
