Elastic Photon Proton Scattering in the 50-{GeV} - 130-{GeV} Range

Breakstone, A.M. ; Cheng, D.C. ; Dorfan, D.E. ; et al.

In the tagged-photon beam at Fermilab, differential cross sections were measured for the elastic scattering of photons on a liquid-hydrogen target. The diffractive forward peak was measured for photon energies between 50 and 130 GeV and |t| values between 0.07 and 1.20 (GeV/c)2. The shape of the diffraction peak is similar to that seen in π−p scattering. The magnitude is that predicted by the optical theorem.

QUASIELASTIC OMEGA PHOTOPRODUCTION AT 50-GEV - 130-GEV

Breakstone, A.M. ; Cheng, D.C. ; Dorfan, D.E. ; et al.
Phys.Rev.Lett. 47 (1981) 1782-1785, 1981.
Inspire Record 173081 DOI 10.17182/hepdata.20625

A study of quasielastic ω photoproduction where the ω was detected in its π0γ decay mode is reported. The recoil proton's angle was detected with a nonmagnetic spectrometer allowing a full reconstruction of the final state. Differential cross sections for 0.1<|t|<1.2 GeV2 are presented, providing a test of the vector-meson dominance model over an extensive energy and momentum transfer range. The shape of the differential cross section agrees with that seen in both elastic γp and πp scattering as expected from this model.

The s and t dependence of incoherent ψ(3100) photoproduction from deuterium has been measured at the Stanford Linear Accelerator Center. ψ(3700) photoproduction and ψ(3100) photoproduction from hydrogen have also been measured.
