Description
Summary:Efficient methods are described for calculating the various “hadron” (fermion bilinear/trilinear) propagators for free lattice fermions. For lattice sizes typical of current Monte Carlo calculations, the large finite-size effects are investigated. Periodic and antiperiodic boundary conditions in the spatial directions appear to yield upper and lower bounds respectively for both the meson-like and baryon-like propagators.
