Book excerpt: We report here differential cross sections for the reaction {gamma}p {yields} K*{sup 0}{Sigma}{sup +} for the first time with high statistics. The measurements were done using the CEBAF Large Acceptance Spectrometer (CLAS) at Jefferson Lab. Data were taken at 3.115 GeV electron beam energy using tagged photons incident upon a liquid hydrogen target. In addition, our analysis provides information about nucleon resonances and their couplings to K* decay. Our data will be used to test predictions of theoretical models of K* production, and to provide constraints on the K*{Sigma}N coupling constant used in these models.

Book excerpt: This analysis of Hall-B data from Jefferson Lab comprises the first high-statistics data on K{sup 0}Sigma{sup +} photoproduction off the proton in the photon energy range from 1.15 to 2.35 GeV.

Available in PDF, EPUB and Kindle. Book excerpt: This theses reports on an experimental search for an exotic hadron, Θ+(1540) pentaquark, which is a genuine exotic hadron with a five-quark system of uuddsbar. The results of this book support that the existence of Θ+ was strongly constrained. The Θ+ pentaquark was searched for via the π- p → K- X reaction using a beam momentum of 2.01 GeV/c at the J-PARC hadron experimental facility, taking advantage of high-statistics and high-resolution compared with previous experiments, some of which claimed the evidence of Θ+. In order to realize a good missing-mass resolution of 2 MeV, the beam spectrometer and superconducting kaon spectrometer were constructed. No clear peak was observed in the missing mass spectrum of the π- p → K- X reaction, and the upper limit of the production cross section was found to be less than 0.28 μb/sr at the 90% confidence level in a mass region of 1500–1560 MeV/c2. This upper limit is an order of magnitude smaller than that of the previous KEK experiment. Compared with a theoretical calculation using the effective Lagrangian approach, the decay width of Θ+ was evaluated. The upper limits on the decay width were estimated to be 0.36 and 1.9 MeV for the Θ+ spin-parity of 1/2+ and 1/2-, respectively. These are quite small for a width of ordinary hadron resonances, and the existence of Θ+ was strongly constrained and is doubtful.

This book was released on 2001-02-28 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume brings together the contributions of experts from different fields within the nuclear physics community. Topics such as rare kaon decays, astrophysics, relativistic heavy ion collisions, and few-GeV electromagnetic probes are covered. The strange quark plays a vital role in understanding such diverse phenomena as CP violation (article by Lincoln Wolfenstein), the “spin crisis” (article by Brad Filipone), and supernova explosions (article by Chris Fryer). Additional topics of interest are parity violation experiments, strangeness content of the proton, and enhanced strangeness production at CERN and RHIC. This unique blend of recent results, with a focus on the role of the strange quark, shows the prominence of strangeness in nuclear physics over the past 50 years.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on the proceedings of the International Symposium on "Strangeness in Nuclear and Hadronic Systems (SENDAI08)," which is the third in a series of symposia on nuclear physics involving strangeness following SENDAI98 and SENDAI03. With the expectation of the completion of new accelerator facilities such as J-PARC and other new experimental facilities, recent theoretical and experimental results and future prospects of strangeness nuclear physics are discussed in great depth by leading experts of the field. The topics involved are electromagnetic production of strangeness, structure and decay of hypernuclei, hyperon-nucleon and hyperon-hyperon interactions, among others. It will also serve as a good textbook for studying the current status of strangeness in nuclear and hadronic physics.

Washington (1997), ECT Trento (1998), Mainz (2001), Pittsburgh (2002) and the LPSC Grenoble (2004). A Baryon Resonance Analysis Group (BRAG) meeting immediately before the workshop focused especially on the physical meaning of bare and dressed scattering matrix singularities. A focus workshop on? photoproduction rounded o? the NSTAR 2007. The goal of NSTAR 2007 was to bring together experts on all areas of physics relevant to baryon spectroscopy, both in experiment and theory. Latest results were presented in 30 plenary talks and 34 parallel contributions, the proceedings of which are collected in this volume. The workshop was attended by 123 scientists of 41 universities and laboratories from 16 countries. Exciting new high-precision data were shown from facilities in Asia, the US and Europe, e.g. BES, BNL, COSY, ELSA, GRAAL, JLab, MAMI and LEPS. Large-acceptance detectors provide complete angular distributions in many reaction channels. Particular emphasis is put on the measurement of single and double polarisation observables such that many new polarization measurements can be expected in forthcoming meetings.
