A comparison of analysis techniques for extracting resonance parameters from lattice Monte Carlo data
Different methods for extracting resonance parameters from Euclidean lattice
field theory are tested. Monte Carlo simulations of the O(4) non-linear sigma
model are used to generate energy spectra in a range of different volumes both
below and above the inelastic threshold. The applicability of the analysis
methods in the elastic region is compared. Problems which arise in the
inelastic region are also emphasised.Comment: 17 pages, 20 figures; clarification and minor corrections added, to
