Abstract:
Hadron spectroscopy on dynamical configurations are faced with the difficulties of dealing with
the mixing of single particle states and multi-hadron states (for large spatial volumes and light
dynamical quarksmasses). It is conceivable that explicitmulti-hadron interpolating operatorswill
be necessary for obtaining sufficiently good overlap on to multi-hadron states in order to extract
the low-lying excitation spectrum. We explore here the feasibility of using four noise diluted
all-to-all quark propagators in the construction of explicit two-hadron operators on quenched,
anisotropic lattices. Our longer term goal is to use these operators on large anisotropic, dynamical
configurations for hadron spectroscopy
