Available in PDF, EPUB and Kindle. Book excerpt: A series of experiments using a polarized beam incident on a polarized frozen spin target (FROST) was conducted at Jefferson Lab in 2010. Results presented here were takenduring the second running period with the FROST target using the CEBAF Large AcceptanceSpectrometer (CLAS) detector at Jefferson Lab, which used transversely-polarizedprotons in a butanol target and a circularly-polarized incident tagged photon beam withenergies between 0.62 and 2.93 GeV. Data are presented for the F and T polarization observablesfor [eta] meson photoproduction on the proton from W = 1.55 GeV to 1.80 GeV.The data presented here will improve the world database and refine theoretical approachesof nucleon structure.

Available in PDF, EPUB and Kindle. Book excerpt: The excitation spectrum of the proton is comprised of many broad overlapping resonances, making investigations of these resonances very challenging. Two excellent tools in helping deconvolve the spectrum are eta and eta-prime meson photoproduction from the proton. Since the beginning of this new millennium, much progress has been made in measuring eta and eta-prime meson photoproduction from the proton. These new measurements are largely in the form of differential cross sections that now cover the first and second resonance regions. In addition to differential cross section data, there have been a comparatively smaller number of beam asymmetry measurements for eta photoproduction. However, these beam asymmetries cover the energy range up to only about E_gamma = 1.5 GeV. In this talk, I will present preliminary Jefferson Lab CLAS data on beam asymmetry for both the eta and eta-prime. I will also discuss how the new measurements will be useful in understanding the structure and exci.

Available in PDF, EPUB and Kindle. Book excerpt: The experimental results of a deuterium bubble chamber photoproduction study of half a million pictures at 5.5 GeV are presented. This experiment has been performed using a monoenergetic and linearly polarized photon beam facility at SLAC. At 5.5 GeV the beam polarization is greater than 90%, and the average FWHM of the beam energy spectrum is 0.6 GeV. The reaction ..gamma..d ..-->.. ..pi ... pi..−d has been studied in detail. A clear sample of ..gamma..d ..-->.. rho°d channel was obtained and from the rho° decay distribution in terms of an extended density matrix which includes correlation with the beam polarization, nine independent density matrix parameters were determined. The study of rho° production and decay in the reaction channel ..gamma..d ..-->.. rho°d was found to proceed almost completely through natural parity exchanges; the contribution from unnatural parity exchanges being only (5.3 +- 4.5)% for momentum transfer absolute value t less than or equal to 0.25 GeV2. For the rho° mass and width, the values (766 +- 5) and (139 +- 11) MeV, respectively were obtained. The rho° production cross section in this channel has been determined to be (9.1 +- 0.8) ..mu..b.
