Lattice QCD calculation of hadron scattering lengths
Abstract
Method of calculating hadron multi-point functions and disconnected quark loop contributions which are not readily accessible through conventional techniques is proposed. Results are reported for π-π, π- N and N- N scattering lengths and the flavor singlet-non singlet meson mass splitting estimated in quenched QCD.
