Resonances in Coupled-Channel Scattering of Light Mesons from Lattice QCD
- Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States); Old Dominion Univ., Norfolk, VA (United States)
Recent calculations of light meson scattering will be presented. Several advances have made it possible to extract coupled-channel hadron-hadron scattering amplitudes in a systematically improvable way using lattice QCD. The methods used in some of these first calculations will be explained in detail, and specific applications will be described. I will focus on channels involving pairs of ?, K, ?,?? mesons. Finite volume energy levels describing these systems are obtained from large correlation matrices that are then diagonalized using the variational method to obtain a spectrum. These finite volume spectra are then used to constrain infinite volume scattering amplitudes that may in turn be analyzed for their pole content to extract resonance properties.
