Determination of Delta resonance parameters from lattice QCD    [PDF]

C. Alexandrou, J. W. Negele, M. Petschlies, A. Strelchenko, A. Tsapalis

A method suitable for extracting resonance parameters of unstable baryons in lattice QCD is examined. The method is applied to the strong decay of the Delta to a pion-nucleon state, extracting the pion-nucleon - Delta coupling constant and Delta decay width.
