J. Ajaka et al., 1998, New measurement of Sigma beam asymmetry for eta meson photoproduction on the proton, Published in Phys. Rev. Lett. 81 (1998)…

The photoproduction of η meson on hydrogen has been measured from threshold to 1100 MeV in GRAAL experiment performed in 1996-1997 at the ESRF in…

The general nodal structure approach is applied to the recent γp⃗→ηp T-asymmetry data from ELSA. The reaction mechanism is found to require, in…

The GRAAL facility produces a highly polarized gamma-ray beam by Compton scattering of laser photons on the electrons of the European Synchrotron…

We present new break-up and coherent data for η meson photoproduction on the deuteron, using a deuterium target and tagged bremsstrahlung photons up…

All sixteen observables for the reaction gamma + p --> eta + p have been investigated from threshold up to 1.2 GeV. The formalism is based on an…
