Multi-hadron operators with all-to-all quark propagators (2008)

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
