Available in PDF, EPUB and Kindle. Book excerpt: Electro- and photoproduction of[omega](783) from a proton target have been measured in the CLAS detector at the Thomas Jefferson National Accelerator Facility in Newport News, VA. The photoproduction data were taken over a photon energy range from 0.5 to 2.3 GeV, while the electroproduction data was obtained over a W range of 1.8--2.5 GeV/c[sup 2]. Preliminary acceptance-corrected center-of-mass angular distributions have been examined for both data sets.

Download or read book Excited Nucleons and Hadronic Structure written by V. Burkert and published by World Scientific. This book was released on 2001 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The conference NSTAR 2000 was part of a series of conferences and workshops that began in New York in 1988. Since then, the field of excited nucleons and hadron structure has developed enormously, and the scope has broadened. Most significantly, new experimental facilities have come into operation, allowing precise measurements of resonance couplings and transition form factors. The search for ?missing? quark model states and gluonic excitations in complex hadronic channels is now possible.On the theory side, new and promising developments have emerged: quark models with meson degrees of freedom, hybrid baryon models, and studies of baryons in the limit of many colors. For the first time, lattice QCD has been employed to calculate masses of excited nucleons. Nucleon resonances are now recognized as providing significant contributions to the nucleon spin sum rules, as well as the Gerasimov-Drell-Hearn and Bjorken integrals, at finite momentum transfer.
Download or read book Near Threshold Electroproduction of the Omega Meson at Momentum Transfer Q2 written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Jefferson Lab kaon experiments E91016/E93018 produced data on both strangeness and vector meson electroproduction. The latter part of the experiments was focused on the electroproduction of the omega meson for momentum transfer Q 2 near 0.5 (GeV/c) 2. This reaction was selected from the inelastic ep channel, H-1 (e, e' p)X, by performing involved signal background separation. Tagging the omega meson production only on electron and proton not only introduced appreciable statistical error but also a sizeable systematic uncertainty due to the background removal. Nevertheless, the analysis yielded angular distributions of the differential cross section in the threshold regime extracted with an unprecedented granularity and relatively small errors.

Book excerpt: Electromagnetic meson production is an important tool in the investigation of the structure of the nucleon. Consequently, a series of meson photo- and electroproduction experiments have been performed with the CLAS detector at Jefferson Lab. In this overview I will report on measurements of cross sections, as well as recent and upcoming measurements of single- and double-polarization observables in meson photoproduction. The data will greatly constrain partial-wave analyses and reduce model-dependent uncertainties in the extraction of nucleon resonance properties.

Download or read book Intersections of Particle and Nuclear Physics written by Zohreh Parsa and published by American Institute of Physics. This book was released on 2000-12-21 with total page 1058 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this meeting, as with the six previous conferences in this series, was to bring together particle and nuclear physicists to share scientific reports and discuss areas of research which overlap both disciplines. The need for such an interdisciplinary conference was recognized by Alan D. Krisch and Malcolm H. MacFarlane, founding fathers of the CIPANP series. Its relevance has steadily grown as the areas of overlap between particle and nuclear physics have increased. In addition, the success of the standard model has provided a common underpinning for both disciplines as well as similar fundamental goals. Indeed, Quantum Chromodynamics (QCD) has proven to be "the" theory of strong interactions. As such, it forms the basis for nuclear physics as well as high energy hadronic interactions. Topics included are: QCD spectroscopy and dynamics, relativistic heavy ions, QCD and nuclear structure, lepton-hadron and hadron-hadron scattering, heavy quark and heavy lepton physics, spin physics, nuclear and particle astrophysics, neutrinos, accelerators, facilities and detectors, as well as tests of fundamental symmetries.
Download or read book Deeply Pseudoscalar Meson Electroproduction with CLAS and Generalized Parton Distribution written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We discuss the recent data of exclusive $\pi^0$ (and $\pi^+$) electroproduction on the proton obtained by the CLAS collaboration at Jefferson Lab. It is observed that the cross sections, which have been decomposed in $\sigma_T+\epsilon\sigma_L$, $\sigma_{TT}$ and $\sigma_{LT}$ structure functions, are dominated by transverse amplitude contributions. The data can be interpreted in the Generalized Parton Distribution formalism provided that one includes helicity-flip transversity GPDs.

Book excerpt: Deeply virtual Compton scattering, cross sections and asymmetries for the pi^0 and eta exclusive electroproduction in a very wide kinematic range of Q^2, t and x_B have been measured with CLAS (Jlab). Initial analyzes already are showing remarkable results. These data will help us to better understand the transition from soft to hard mechanisms.
