Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation I describe a study of double-charm and charm-strange baryons based on data collected with the BABAR Detector at the Stanford Linear Accelerator Center. In this study I search for new baryons and make precise measurements of their properties and decay modes. I seek to verify and expand upon double-charm and charm-strange baryon observations made by other experiments. The BABAR Detector is used to measure subatomic particles that are produced at the PEP-II storage rings. I analyze approximately 300 million e+e- → c{bar c} events in a search for the production of double-charm baryons. I search for the double-charm baryons?{sub cc} (containing the quarks ccd) and?{sup ++}{sub cc} (ccu) in decays to?+{sub c}K−?+ and?+{sub c}K−?+?+, respectively. No statistically significant signals for their production are found, and upper limits on their production are determined. Statistically significant signals for excited charm-strange baryons are observed with my analysis of approximately 500 million e+e- → c{bar c} events. The charged charm-strange baryons?{sub c}(2970)+,?{sub c}(3055)+,?{sub c}(3123)+ are found in decays to?+{sub c}K−?+, the same decay mode used in the?+{sub cc} search. The neutral charm-strange baryon?{sub c}(3077)° is observed in decays to?+{sub c}K?−. I also search for excited charm-strange baryon decays to?+{sub c}K8,?+{sub c}K−,?+{sub c}K8?−?+, and?+{sub c}K−?−?+. No significant charm-strange baryon signals a f h these decay modes. For each excited charm-strange baryon state that I observe, I measure its mass, natural width (lifetime), and production rate. The properties of these excited charm-strange baryons and their decay modes provide constraints for phenomenological models of quark interactions through quantum chromodynamics. My discovery of the two new charm-strange baryons?{sub c}(3055)+ and?{sub c}(3123)+ influences our theoretical understanding of charm-strange baryon states.

Book excerpt: The strong decays of excited nonstrange baryons into the final states [Lambda]K, [Sigma]K, and for the first time into [Lambda](1405)K, [Lambda](1520)K, [Sigma](1385)K, [Lambda]K{sup *}, and [Sigma]K{sup *}, are examined in a relativized quark pair creation model. The wave functions and parameters of the model are fixed by previous calculations of N[pi] and N[pi][pi], etc., decays. The results show that it should be possible to discover several new negative parity excited baryons and confirm the discovery of several others by analyzing these final states in kaon production experiments. They also establish clear predictions for the relative strengths of certain states to decay to [Lambda](1405)K and [Lambda](1520)K, which can be tested to determine if a three-quark model of the [Lambda](1405)K is valid. The authors results compare favorably with the results of partial wave analyses of the limited existing data for the [Lambda]K and [Sigma]K channels. They do not find large [Sigma]K decay amplitudes for a substantial group of predicted and weakly established negative-parity states, in contrast to the only previous work to consider decays of these states into the strange final states [Lambda]K and [Sigma]K.

Book excerpt: No six-quark bound hadron, (other than the loosely bound deuteron) has been observed, despite several experimental searches. Some models of quark dynamics predict the existence of such a state, the doubly-strange six-quark H dibaryon (uuddss) being the most likely. The mass of the H would be between that of the deuteron and the 2m{sub?} strong interaction decay threshold. In 1992, Experiment E888 at Brookhaven National Labs̀ Alternating Gradient Synchrotron collected data to search for this particle. The detector consisted of a two-arm spectrometer with drift chamber tracking and two magnets for momentum analysis, scintillator hodoscope triggering, Cerenkov particle identification, an electromagnetic calorimeter, and a muon hodoscope and rangefinder. The experiment searched for the decay? → p?− from the weak decays of H →?n and H →?°n (followed by?° →??). This search was sensitive to weakly decaying H dibaryons with lifetimes from 6-230 us with production cross-sections greater than -2?b/steradian.
