The masses and widths of the nucleons (baryons composed three and quarks) are well measured and reasonably well predicted by theory. To a lesser extent, the same is true in the hyperon (composed of , , and quarks) sector. However, in the charm sector, these measurements are much less advanced. To extrapolate the properties of other charmed baryons, it is often useful to have accurate measurements of both the mass and width of a single state. Furthermore, as shown in sc_width, the mass and width of a strongly decaying baryon are related in the models through the available phase space for the decay. The baryons are good candidates for such measurements since they are the most copiously produced excited charmed baryons. It is this which motivates the analyses presented in this thesis.
