The Ep -> E'P Eta Reaction At And Above The S-11(1535) Baryon Resonance
PHYSICAL REVIEW LETTERS(2001)
Abstract
New cross sections for the reaction ep --> ep eta are reported for total center of mass energy W = 1.5-1.86 GeV and invariant momentum transfer Q(2) = 0.25-1.5 (GeV/c)(2). This large kinematic range allows extraction of important new information about response functions, photocouplings, and etaN coupling strengths of baryon resonances. Newly observed structure at W similar to 1.65 GeV is shown to come from interference between S and P waves and can be interpreted with known resonances. Improved values are derived for the photon coupling amplitude for the S-11(1535) resonance.
