In order to really understand QCD and hence test whether it is the complete theory of the strong interaction, we must determine the spectrum of mesons and baryons that it implies and test those spectra against high quality experimental measurements. The complete combined analysis of available experimental data on the photoproduction of nucleon reso­ nances is the 2009 milestone in Hadronic Physics (HP), and the measurement of the elec­ tromagnetic properties of the low­lying baryons is an HP 2012 milestone; the experimental investigation of the meson resonance spectrum, and in particular the search for mesons with exotic quantum numbers, is the aim of the GlueX Collaboration at JLab@12GeV. Given the current intense experimental e#orts in hadron spectroscopy, the need to predict and understand the hadron spectrum from first principles calculations in QCD is clear. Hence, our goal in this proposal is a comprehensive study of the meson and baryon spectrum, employing the anisotropic clover gauge configurations generated under the proposal of Edwards et al..; in addition we will perform the first investigation of the radiative transitions between mesons comprised of light quarks, providing vital input to the expectations for the GlueX experiment.
