Inspire Record 69020 DOI 10.17182/hepdata.21506

We have studied the reaction e−+p→e−+π++n by detecting the final electron and pion in coincidence. Data are presented in the region of virtual photon mass squared from -0.18 to -1.2 GeV2, and virtual photoproduction center-of-mass energy and angle from 1.85 to 2.50 GeV and 0 to 20°, respectively.

Photoproduction of pi+ Mesons at 3.4 and 5.0 BeV

Joseph, P.M. ; Hicks, N. ; Litt, L. ; et al.
Phys.Rev.Lett. 19 (1967) 1206-1209, 1967.
Inspire Record 52485 DOI 10.17182/hepdata.21755

We report measurements of the photoproduction from hydrogen of single π+ mesons at gamma-ray energies of 3.4 and 5.0 BeV and at laboratory angles of 5.1°, 7.1°, 9.9°, and 15.1°. The s dependence at fixed t is derived for momentum transfers of -0.20, -0.37, and -0.70 BeV2. The pion data are compared with a Reggeized one-pion-exchange model.

Measurements of the photoproduction from hydrogen of single K + mesons at gamma ray energies of 3.4 and 5.0 GeV and at laboratory angles of 5.1°, 7.1°, 9.9° and 15.1° are reported. The s dependence at fixed t is derived for momentum transfers of −0.25 and −0.37 (GeV) 2 .

Elastic electron - Proton Scattering at Large Four Momentum Transfer

Kirk, Paul N. ; Breidenbach, Martin ; Friedman, Jerome I. ; et al.
Phys.Rev.D 8 (1973) 63-91, 1973.
Inspire Record 73424 DOI 10.17182/hepdata.21999

Electron-proton elastic-scattering cross sections have been measured at the Stanford Linear Accelerator Center for four-momentum transfers squared q 2 from 1.0 to 25.0 (GeVc)2. The electric (GEp) and magnetic (GMp) form factors of the proton were not separated, since angular distributions were not measured at each q 2. However, values for GMp were derived assuming various relations between GEp and GMp. Several theoretical models for the behavior of the proton magnetic form factor at high values of q 2 are compared with the data.

A COMPARISON OF ELECTRON - PROTON AND POSITRON - PROTON ELASTIC SCATTERING AT FOUR MOMENTUM TRANSFERS UP TO 5.0-GeV/c**2

Mar, J. ; Barish, Barry C. ; Pine, Jerome ; et al.
Phys.Rev.Lett. 21 (1968) 482-484, 1968.
Inspire Record 52726 DOI 10.17182/hepdata.21724

Measurements of the ratio (R) of positron-proton and electron-proton elastic-scattering cross sections have been made, with the square of the four-momentum transfer (q2) equal to 0.20, 0.69, 0.73, 1.54, 2.44, 3.27, 3.79, and 5.00 (GeV/c)2. The measurements, after radiative corrections, are consistent with R=1, with standard errors ranging from ±0.016 to ±0.123. The results give limits for the size of the two-photon effects.

The reaction γ p → K + K − p has been investigated with tagged photons in the energy range of 20 < E γ < 70 GeV. A structure in the 1.7 GeV mass region is observed and interpreted in terms of a recurrence of the ø.

Measurements of small angle proton proton elastic scattering at the cern intersecting storage rings

Amaldi, U. ; Biancastelli, R. ; Bosio, C. ; et al.
Phys.Lett.B 36 (1971) 504-508, 1971.
Inspire Record 69145 DOI 10.17182/hepdata.28393

Proton-proton elastic scattering has been measured over the angular range 7 to 16 mrad at centre-of-mass energies of 31, 45 and 53 GeV using the CERN Intersecting Storage Rings. The results indicate that the diffraction peak has continued to shrink with increasing energy, but not as fast as suggested by the results at lower energies.
