PHOTOPRODUCTION OF pi0 WITH PLANE POLARIZED 3-Gev PHOTONS

Bellenger, D. ; Bordelon, R. ; Cohen, K. ; et al.

Phys.Rev.Lett. 23 (1969) 540, 1969.

Inspire Record 55099 DOI 10.17182/hepdata.21666

The cross section for photoproduction of π0 mesons was measured at a photon energy of 3 GeV and squared four-momentum transfer (t) of -0.1 to -1.2 (GeV/c)2 using plane-polarized photons. The asymmetry was found to be consistent with +1.0 for t values above -0.4 and below -1.1. For −0.4<~t<~−1.0 there is a dip in the asymmetry and at t=−0.6 it drops to 0.55 ± 0.15. This result precludes a simple Regge model with ω0 and B; a theoretical description requires Regge cuts or an ω′ exchange.

Photoproduction of Single Charged Pions from Deuterium and Hydrogen

Bar-Yam, Z. ; de Pagter, J. ; Hoenig, M.M. ; et al.

Phys.Rev.Lett. 19 (1967) 40-42, 1967.

Inspire Record 52325 DOI 10.17182/hepdata.21751

Differential cross sections for the photoproduction of single charged pions from deuterium and hydrogen have been measured at pion center-of-mass angles between 30° and 90° and at photon energies between 3.0 and 3.7 GeV. The ratio of π− to π+ cross sections from deuterium is found to be appreciably smaller than 1.

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.
