Recently it has become possible to obtain coupled-channel scattering amplitudes using lattice QCD. Using a large basis of operators we are able to obtain a reliable finite volume spectrum describing the \pi-K, \eta-K coupled system. Utilising the finite volume formalism proposed by Luescher and extended by several others, we are able to describe the spectra
from each lattice symmetry group...

Photo-production experiments with the CEBAF Large Acceptance Spectrometer (CLAS) at the Thomas Jefferson National Laboratory produce data sets with unprecedented statistics of light mesons. With these data sets, measurements of transition form factors for $\eta$, $\omega$, and $\eta^\prime$ via conversion decays can be performed using a line shape analysis on the invariant mass of the final...

Over the past two decades, meson photo- and electroproduction data of unprecedented quality and quantity have been measured at electromagnetic facilities worldwide, at investments of many millions
of dollars. By contrast, the meson-beam data for the same hadronic final states are mostly outdated and largely of poor quality, or even non-existent, and thus provide inadequate input to help...

Recent results in computing excited state energies and meson-meson scattering phase shifts in lattice QCD
are presented. A stochastic method of treating the low-lying modes of quark propagation that exploits Laplacian
Heaviside quark-field smearing makes such studies possible now. Levels are identified using a variety of
probe interpolating operators.
