Inclusive analyses provide a different insight into our understanding of weak decayphysics. In this thesis, I experimentally determine inclusive decay properties of charmedD mesons. I also use exclusive decay predictions from a variety of theoretical modelsto make predictions about inclusive properties. Both experimental and theoretical realmsbenefit from the new techniques presented in this thesis.
Inclusive properties derived are the multiplicity distributions, average multiplicitiesand inclusive branching ratios of charged particles, charged and neutral kaons, andcharged pions. The center-of-mass momentum spectra of charged and neutral kaonsare also obtained. Additionally, in the theoretical realm only, the inclusive properties ofneutral pions, and the center-of-mass momentum spectra of charged and neutral pionsare determined.
The experimental analysis, which uses data from the Mark III experiment at theStanford Linear Accelerator Center, employs an unfold technique utilizing fold matricesto obtain the charged particle and kaon properties. A new, enhanced unfold techniqueinvolving fold tensors obtains the first-ever results for the inclusive charged pion properties.The average strange quark contents and the average charged lepton multiplicitiesof the D+, D0 , and D+s are also presented.
In the theoretical analysis, the exclusive decay mode predictions from the factorizationmodel of Bauer, Stech and Wirbel; the quark diagram scheme of Chau and Cheng; andthe QCD sum rules model of Blok and Shifman are processed to determine inclusiveproperties. It is hoped that an examination of a model's inclusive predictions will leadto a better understanding of the model. I also derive inclusive predictions from the Dmeson exclusive branching ratios compiled by the Particle Data Group.
