Abstract

Lattice hadron spectroscopy is crucial to inform and direct a new generation of experiments. Useful calculations require control of both statistical and systematic uncertainties. In these lectures selected methods for lattice hadron spectroscopy are discussed in detail. The lectures aim to describe all aspects of a calculation from quark propagation to fitting and interpreting data. After some motivation for lattice spectroscopy, the path integral approach and construction of correlation functions are discussed. There are detailed discussions of techniques for quark propagators, including new developments in calculations of all-to-all propagators. Lattice and continuum symmetries are contrasted and techniques for spin identification in lattice calculations are discussed in some detail. Design and construction of optimal operators as well as fitting and systematic errors are addressed. Finally, open problems and challenges are described focusing on resonances and scattering states.

Keywords

Lattice Calculation Quark Propagator Quark Propagation Anisotropic Lattice Operator Construction 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
