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.

    Lattice QCD computation of hadronic tensor yields consistent nucleon Sachs electric form factor and extracts transition form factors to the Roper resonance region for inclusive cross sections.

    hep-lat 2024-11 conditional novelty 6.0 of 10

    The ratio method, tuned with twisted boundary conditions, extracts a psi(3770) -> D D mixing amplitude from two N_f=2 ensembles and gives Gamma = 24.2(6.4) MeV, but with unquantified systematic errors.
