ANALYSIS OF THE REACTION GAMMA-RAY + PROTON TO ETA-BARYON + PROTON NEAR THRESHOLD.
Abstract
The recent measurements of eta photoproduction 'gamma-ray + proton to eta-baryon + proton', reveal an enhancement of the cross section, sigma-gamma, just above threshold. This is very similar to the enhancement of the 'negative-pion + proton to eta-baryon + neutron' cross section, sigma-pi, which we have shown can be explained by an S wave resonance with an approximate mass and width of 1560 and 150 MeV respectively. It is shown that this resonance can also explain the enhancement of sigma-gamma.
