“…Taking PCV to be the endpoint instead of PCN gives the value 25 µr, however, the real gain in resolution probably comes from the fact that the PCF chambers help constrain the fit. to a detailed map of the CCM field [Sal86,Salvarani]. The hits supplied by pattern recognition are• subjected first to local fits.…”

Neutral vector mesons share the quantum numbers as the photon, consequently, they are produced copiously in diffractive interactions of photons. The lightest of these, the p 0 meson, have been studied in the absorption of high energy virtual photons on hydrogen and deuterium. The mass spectrum, decay distribution, and momentum transfer to the target nucleon has been studied as a function of the kinematic variables. The interference of the two-pion resonance and continuum is constant as a function of the virtual photon mass, Q 2 • The p 0 polarization changes from purely transverse at low Q 2 to predominantly longitudinal at high Q 2 • The azimuthal decay distribution conforms to the expected form, including terms for transverse-transverse and transverse-longitudinal interference. The diffractive slope parameter declines only slightly with Q 2 , indicating that for Q 2 up to approximately 4 GeV 2 , production of exclusive p 0 mesons is_ a diffractive process. .- .-I do not know whom to thank first-my friend Silhacene Ai'd, or my friend John Ryan. John and I share a natural similarity of outlook and attitude which helped me develop and preserve a critical skepticism essential to good science. Silhacene reminded me what clear, logical thinking is, especially as expressed in the rigorous language of mathematics. I gratefully acknowledge the profound influence each of you has had on my experiences here. I won't forget it. Second only to John and Silhacene, my advisor Frank Pipkin has supported and encouraged my efforts during the darkest and the brightest times of the analysis of the 1987-88 data. He has shown great patience and understanding, allowing me to make my mistakes, and to learn from them, and at the same time showing keen interest in any progress, no matter how modest. Dick Wilson also has helped many times, acting as a "co-advisor," always making useful and illuminating suggestions. Some of the other students and post-docs have been real comrades through the years. I a.m. especially grateful for many conversations with David Jaffe, Anwar Bhatti, and Mark Baker. Several other students played vital roles in getting the data analyzed, including Alex Salvarani, Doug Jansen, Uwe Ecker, Steve Magill, Martin Erdmann, Steve O'Day, and Erik Ramberg. Clive Halliwell miraculously kept the students moving basically forward as a group, despite frequent opposition. Harry Melanson and Steve Wolbers were on top and in charge of much of the reconstruction code, and their contributions at the most basic levels were appreciated by many. Mark Adams' insistence on checks and cross-checks helped keep the quality of analysis high. I wish to extend special acknowledgment and thanks to Shuichi Kunori and Hugh Montgomery, for their boundless enthusiasm for physics, which they gladly communicated and shared with the rest of us. I benefited many times from discussions with them. Before and during the 1987 run, I learned a lot from Richard Nickerson, particularly a.bout the importance of and challenges in building good hardware. I als...
