Description
Gauge theories with some or all of space-time discretized may be recast as coupled integrable 1+1-dimensional
field theories, whose exact S-matrices and form factors are known. Information about the 1+1-dimensional system can be used to extract string tensions and mass spectra for weakly-coupled (but anisotropic) 2+1-dimensional gauge theories. For 3+1-dimensional gauge theories, weak-coupling assumptions no longer work as effectively, but a qualitative string-parton picture appears. I will discuss briefly how the methods may be extended, in principle, to the isotropic case.
