Available in PDF, EPUB and Kindle. Book excerpt: Data are presented for the E polarization observable for eta meson photoproduction on the proton from threshold (W=1500 MeV) to W=1900 MeV. Comparisons to the partial wave analyses of SAID and Bonn-Gatchina along with the isobar analysis of eta-MAID are made. These results will help distinguish between current theoretical predictions and refine future theories.

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: In recent years, there has been much interest in the possible existence of the N*(1685) narrow nucleon resonance, as predicted by the chiral soliton model. Several eta photoproduction experiments have been performed that rely on extracting neutron observables from deuteron target data. These have shown some evidence of narrow structure, however, no structure was observed in cross section measurements on the proton channel. Within the A2 collaboration at the MAMI accelerator in Mainz, Germany, a more detailed study has been undertaken using eta photoproduction on a liquid hydrogen target, and is the subject for this thesis. The study utilised the high resolution and high precision possible with the A2 detector setup, in an attempt to overcome the predicted low photocoupling between the N*(1685) and the proton. The MAMI electron beam was used to produce bremsstrahlung photons, the energies of which are determined by detecting the recoil electrons in the Glasgow-Mainz Tagged Photon Spectrometer. The reaction products from the interaction of the photon beam and liquid hydrogen were detected by the Crystal Ball and TAPS calorimeters. The gamma proton to eta proton reaction channel was identified via the 3 neutral pion decay branch. The reaction cross section was measured between E = 707 and 1477 MeV. Both differential and total cross sections have been presented with a particular emphasis on the centre of mass energy range around 1685 MeV. The peak structure seen on the neutron channel is not observed in the case of the proton. However, a dip in the cross section is observed, which is more prominent at forward polar angles. The leading models are not fully able to reproduce the data in this energy region. As such, given the high energy resolution of the measurement the results can be used to constrain future models and in doing so aid the understanding of the nucleon's resonance spectrum.

Book excerpt: Differential cross sections for the reaction[gamma]p[yields] np have been measured for incident photon energies from 0.75 to 1.95 GeV. Data were taken using the CLAS spectrometer and tagged photon facility at Jefferson Lab. The data provide the first extensive measurements of angular distributions for this process above the S11 (1535) resonance in the range up to W= 2.1 GeV.
