Demonstrated extraction of scattering phase shifts from lattice simulations.
Reviewed recent advances in lattice techniques for resonance analysis.
Abstract
I discuss how masses and widths of hadron resonances are extracted from lattice QCD. Recent lattice results on the light, strange and charm meson resonances are reviewed. Their properties are revealed by simulating the corresponding scattering channels pi-pi, K-pi and D-pi on the lattice and extracting the scattering phase shifts. In particular we address the resonances rho, D0*(2400), D1(2430), K*, kappa and K0*(1430).
