MEASUREMENTS OF PI0 PHOTOPRODUCTION CROSS-SECTIONS FOR INCIDENT GAMMA-RAY ENERGIES OF 2.0-Gev/c TO 5.0-Gev/c

Bolon, G.C. ; Garelick, C. ; Homma, S. ; et al.
Phys.Rev.Lett. 18 (1967) 926, 1967.
Inspire Record 51286 DOI 10.17182/hepdata.21770

Cross sections for the reaction γ+p→π0+p for incident gamma-ray energies of 2.0 to 5.0 GeV and for baryon four-momentum transfers squared of 0.5 to 4.0 (GeV/c)2 are presented. The results are compared with theoretical predictions based on Reggeized vector-meson exchange.

Photoproduction cross sections for $\pi^+$ and $K^+$ mesons at 3.4 to 4.0 {GeV} and their comparison with {SU(3)}

Elings, V.B. ; Cohen, K.J. ; Garelick, D.A. ; et al.
Phys.Rev. 156 (1967) 1433-1443, 1967.
Inspire Record 51624 DOI 10.17182/hepdata.406

The differential cross sections for the photoproduction reactions γ+p→π++n, γ+p→K++Λ0, and γ+p→K++Σ0 have ben measured for incident laboratory photon energies between 3.4 and 4.0 GeV and for meson center-of-mass angles from about 25° to 45°. The reactions were studied by observing only the charged mesons. The momenta, velocities, and angles of the mesons were measured with a magnetic spectrometer, and the equivalent of nearly monochromatic gamma rays was obtained by performing bremsstrahlung subtractions. The cross sections agree with the inequality predicted from unbroken SU(3). The measured behavior of dσdt as a function of t shows similarities to that observed in studies of mesonnucleon scattering.

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.

PHOTOPRODUCTION OF eta0 MESONS AT 4-Gev

Bellenger, D. ; Deutsch, S. ; Luckey, David ; et al.
Phys.Rev.Lett. 21 (1968) 1205, 1968.
Inspire Record 53018 DOI 10.17182/hepdata.21703

We have measured η0 photoproduction at 4 GeV. We find our results to be consistent with a theoretical preduction relating this cross section to ω0 production by π mesons using a vector-dominance model; there is no evidence for a dip or change of slope at −t=0.6 as seen in π0 photoproduction.

Differential Cross Sections in Eta Photoproduction from 0.8 to 1.45 GeV

Bloom, E.D. ; Heusch, C.A. ; Prescott, C.Y. ; et al.
Phys.Rev.Lett. 21 (1968) 1100-1103, 1968.
Inspire Record 54471 DOI 10.17182/hepdata.21721

The cross section for the process γp→pη was studied from 0.8- to 1.45-GeV incident photon energy at center-of-mass angles from 50 to 90°. The data cover a range of energies well beyond previous measurements. The results will aid in the study of I=12 nucleon isobars.

The slope parameter of the differential cross-section of elastic p-p scattering in energy range 12-70 gev

Beznogikh, G.G. ; Buyak, A. ; Iovchev, K.I. ; et al.
Phys.Lett.B 30 (1969) 274-275, 1969.
Inspire Record 56659 DOI 10.17182/hepdata.28895

The measurements of the differential cross section of elastic p-p scattering in relative units were performed in the energy range of 12–70 GeV. The values of the slope parameter were obtained from this data. It was shown that the slope parameter of the differential p-p scattering is monotonously increasing when the proton energy rises in the range 12–70 GeV. We have obtained the slope Pomeranchuk's pole trajectory from this data: α′ p = 0.40 ± 0.09.
