Improving the signal-to-noise-ratio in lattice gauge theories [PDF]
, 1997 Renormalization of composite fields is employed to suppress the statistical noise in lattice gauge calculations. We propose a new action which differs from the standard Wilson action by ''irrelevant'' operators, but suppresses the fluctuations of the ...
