2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/147812We present the lattice gauge theory approach to evaluating non-perturbative hadronic interactions from first principles. We discuss applications to glueballs, inter-quark potentials, the running coupling constant, the light hadron spectrum and the pseudoscalar decay constant $f_P$.to appear in Proceedings of the NATO Advanced Study Institute on Hadron Spectroscopy and the Confinement Problem June 27 - July 7, 1995; 19 pages, latex, 6 uuencoded compressed postscript figures; also available in ftp://suna.amtp.liv.ac.uk/pub/cmi/nato_schoolHigh Energy Physics - LatticeHigh Energy Physics - Phenomenologytext
