Recent work by Prof. Morningstar and collaborators has been highlighted in the Pittsburgh Supercomputer Center's "Projects in Scientific Computing".  The Hadron Spectrum Collaboration (which includes Morningstar and collaborators at Jefferson Lab, University of Maryland College Park, University of the Pacific at Stockton, Trinity College in Dublin) has computed the masses of a large number of excited states of the nucleon using Monte Carlo simulations of quantum chromodynamics on a space-time lattice.  Most of their results are first-time calculations: the masses of many of the excited states studied had never been computed before using lattice QCD with quark loops.  The article is entitled "Excited states of the strong force".
