CLEO Contributions to Tau Physics
No full textIntroduction Over the last dozen years, the CLEO Collaboration has made use of data collected by the the CLEO-II detector [1] to measure many of the properties of the tau lepton and its neutrino. Now that the experiment is making a transition from operation in the 10 GeV (B factory) region to the 3-5 GeV tau-charm factory region [2], it seemed to the author and the Tau02 conference organizers to be a good time to review the contributions of the CLEO experiment to tau physics. We are consciously omitting results from CLEO-I (data taken before 1989). The author has chosen to take a semi-critical approach, emphasizing both the strengths and weaknesses of tau physics at CLEO: past, present, and future. 2. Tau Production at 10 GeV We begin by discussing a topic on which CLEO has not published: tau pair production. In e e collisions, one can study taus in production and/or decay. The production reaction is governed by wellunderstood QED. As such, it is not terribly interesti
The decay tau -> 3 pi nu(tau), as a probe of the mechanism of dynamical chiral symmetry breaking
No full textThe decays tau --> 3 pi + nu(tau) are analyzed at one loop order in the framework of Generalized Chiral Perturbation Theory, in order to test the sensitivity to the size of spontaneous chiral symmetry breaking parameters, contained in the S-wave. The latter, due to a kinematical suppression, at threshold, of the P-wave, is relatively large enough to be detectable at high-energy machines, through azimuthal left-right asymmetries. This quantity (for the pi(-) pi(-) pi(+) mode), integrated from threshold to Q(2) = 0.35 GeV2, varies from (17 +/- 3)% in the standard case of large condensate up to (40 +/- 5)% in the extreme case of tiny condensate. The feasibility of such measurement at high luminosity colliders (e.g., CLEO) is discussed. This method provides an independent cross-check of forthcoming experimental determination of the two-light-flavor chiral condensate, based on low-energy pi pi scattering
Development of titanium-based scaffolds for spinal prosthesis
No full textThe author was selected to join Assistant Professor Cleo Choong research group together with a collaboration project with Singapore Institute of Manufacturing Technology, Singapore for his Final Year Project with the project title as “Development of Titanium-based Scaffolds for Spinal Prosthesis”. Throughout this project, the author was under the guidance of Assistant Professor Cleo Choong as School of Materials Science & Engineering supervisor, Nanyang Technological University as well as Dr. He Zeming and Dr. Saeed Maleksaeedi as direct institute supervisors.
During this 1-year of research work, the author had been exposed to various types of learning experiences as well as hands-on opportunities for example seeing how the research milestones were planned and taking charged of carrying it out, using different types of characterisation testing machines such as Instron materials characterisation machine, Stylus Profilometer (Taylor-Hobson Form Talysurf Series 2) etc., understanding various process flows required in a research in order to link up all the research data and results via program used for data analysis.
Lastly the experience gained had enabled the author to further enhance his technical knowledge, develop a better safety culture as well as make learning a more enjoyable and fun journey. Besides, the author experienced culture differences as he worked together with exchange students from University of Sydney, Australia, improving his communication skills in the process.Bachelor of Engineering (Materials Engineering

Charm inputs from CLEO-c for γ measurements
No full textThe measurements of D0 strong phase parameters in quantum correlated ψ(3770) → D0D̄0 decays by the CLEO collaboration are presented here. These measurements can be used as inputs to model independent measurements of the unitary angle γ. Measurements of strong phase difference parameters in the decays D0 → K- π+, D0 → K- π+ π0, D0 → K- π+ π+ π-, D0 → KSK - π+, D0 → KSπ+π -, and D0 → KSK+K- decays are described along with their impact on future measurements of 7. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-Non Commercial-Share Alike Licence
T. S. Eliot and Indic Traditions
No full textT. S. Eliot's allusions to Indic philosophy in several poems - from the Sanskrit ending of The Waste Land to the 'What Krishna meant' section of Four Quartets - have puzzled and intrigued readers since the poems first appeared. In T. S. Eliot and Indic Traditions, Professor Cleo McNelly Kearns places Eliot's lifelong interest in Indic philosophy and religion in the context of his concomitant studies in Western philosophy and his views on literary theory and poetic practice. The author establishes the depth and extent of his knowledge not only of Sanskrit and Pali texts but also of the scholarly tradition through which they were interpreted in the West. She explores as well Eliot's keen sense of the important distinctions between specific schools of thought. Kearns concludes that Eliot was less interested in synthesizing various traditions than in comparing texts and traditions for what he called 'the difference they can make to one another'.</jats:p
