The values of the differential cross sections for the Compton effect on the proton are given for $\gamma$-quantum energies from ~230 to ~250 MeV. These values of the cross sections are the result of a more accurate analysis and of making absolute the experimental data obtained by us earlier.

The angular distribution of 24 7 ± 10 Mev gamma rays produced in the synchrotron of the Lebedev Physics Institute, which were scattered elastically on hydrogen, has been investigated. Differential cross sections were obtained for c.m. scattering angles of 148, 132, 108, 93, 70, and 55°. The experimental results are compared with calculations based on onedimensional dispersion relations with an additional contribution from a single-meson intermediate state taken into account.

Polarization transfer in proton Compton scattering at high momentum transfer

The Jefferson Lab Hall A collaboration Hamilton, D.J. ; Mamyan, V.H. ; Aniol, K.A. ; et al.

Inspire Record 660894 DOI 10.17182/hepdata.19389

Compton scattering from the proton was investigated at s=6.9 (GeV/c)**2 and \t=-4.0 (GeV/c)**2 via polarization transfer from circularly polarized incident photons. The longitudinal and transverse components of the recoil proton polarization were measured. The results are in excellent agreement with a prediction based on a reaction mechanism in which the photon interacts with a single quark carrying the spin of the proton and in disagreement with a prediction of pQCD based on a two-gluon exchange mechanism.

Compton scattering cross-section on the proton at high momentum transfer

The Hall A collaboration Danagoulian, A. ; Mamyan, V.H. ; Roedelbronn, M. ; et al.
Phys.Rev.Lett. 98 (2007) 152001, 2007.
Inspire Record 743383 DOI 10.17182/hepdata.31472

Cross-section values for Compton scattering on the proton were measured at 25 kinematic settings over the range s = 5-11 and -t = 2-7 GeV2 with statistical accuracy of a few percent. The scaling power for the s-dependence of the cross section at fixed center of mass angle was found to be 8.0 +/ 0.2, strongly inconsistent with the prediction of perturbative QCD. The observed cross-section values are in fair agreement with the calculations using the handbag mechanism, in which the external photons couple to a single quark.

Proton Compton effect by polarized photons at 90 degrees in the c.m. system in the first resonance region

For the reaction γ+p→γ′+p′ (proton Compton effect), we have measured the ratio dσIIdσ⊥ between the cross sections for linearly polarized photons, using the coherent bremsstrahlung beam of the Frascati electron synchrotron. At 90° in the c.m. system and in the photon energy region 300≤K≤335 MeV, we find dσIIdσ⊥=2.1−0.4+0.5. In the absence of theoretical predictions based on the dispersive theory in this energy region, this result is compared with the values obtained using an isobaric model, taking into account various possible intermediate states.
