Abstract

The γp→ηp reaction has been measured with the Crystal Ball and TAPS multiphoton spectrometers in the energy range from the production threshold of 707 MeV to 1.4 GeV (1.49≤W≤1.87 GeV). Bremsstrahlung photons produced by the 1.5-GeV electron beam of the Mainz Microtron MAMI-C and momentum analyzed by the Glasgow tagging spectrometer were used for the η-meson production. Our accumulation of 3.8×106 γp→ηp→3π 0p→6γp events allows a detailed study of the reaction dynamics. The γp→ηp differential cross sections were determined for 120 energy bins and the full range of the production angles. Our data show a dip near W=1680 MeV in the total cross section caused by a substantial dip in η production at forward angles. The data are compared to predictions of previous SAID and MAID partial-wave analyses and to the latest SAID and MAID fits that included our data.
