The E687 collaboration Frabetti, P.L. ; Paolone, V.S. ; Yager, P.M. ; et al.
Phys.Lett.B 316 (1993) 197-206, 1993.
Inspire Record 359356 DOI 10.17182/hepdata.28834

Measurements of elastic photoproduction cross sections for the J / ψ meson from 100 GeV to 375 GeV are presented. The results indicate that the cross section increases slowly in this range. The shape of the energy dependence agrees well with the photon-gluon fusion model prediction.

COMPTON EFFECT ON pi- MESON

Antipov, Yu.M. ; Batarin, V.A. ; Bessubov, V.A. ; et al.
Z.Phys.C 24 (1984) 39, 1984.
Inspire Record 193860 DOI 10.17182/hepdata.41183

The reaction π−A→Aπ− γ at 40 GeV/c was studied on “Sigma” spectrometer on six different nuclear targets in the region of four-momentum transfer |t|<0.05 (GeV/c)2. A phenomenon of elastic scattering of pions on the nuclear Coulomb field photons was observed, its total and differential cross sections were measured. The cross section of Compton effect on π−-meson was measured.
