The standard model of particle physics describes interactions of the fundamental constituents of matter up to all energies so far explored in particle accelerators. It includes quantum chromodynamics, the theory that describes the strong nuclear force. The strength of interactions in this theory means the only way to make direct predictions from the theory is to perform numerical investigations of the theory represented on a four-dimensional space-time lattice (lattice QCD). This project will use lattice QCD to measure the masses of particles built from a charm and an anti-charm quark. These heavy states have been the subject of intense experimental scrutiny recently as new measurements do not fit neatly into model predictions. The project will determine the masses of radial and orbital excitations of these particles, as well as the so-called hybrid states that include intrinsic excitations
