      Spectrum of confining strings in SU(N) gauge theories 

      Del Debbio, L.; Panagopoulos, Haralambos G.; Rossi, P.; Vicari, E. (2002)
      We study the spectrum of the confining strings in four-dimensional SU(N) gauge theories. We compute, for the SU(4) and SU(6) gauge theories formulated on a lattice, the string tensions σk related to sources with ZN charge ...
