Backward photoproduction of neutral pions off hydrogen at photon energies between 0.4 and 2.2 gev

Becks, H. ; Feller, P. ; Menze, D. ; et al.

The differential cross section has been measured for the reaction γ +p→p+ π o at the Bonn 2.5 GeV electron synchrotron in the energy range from 0.4 to 2.2 GeV for a c.m. angle of 150 degrees. The protons were detected in a magnetic spectrometer system. The excitation curve shows a distinct resonance structure. The total corrections to the counting rate are about 3%. The contribution of the process γ +p→p+2 π was separated. The uncertainty of this separation leads to an error of about 4% in the cross section.

Topological and channel cross sections are given for the more common final states produced in K − p interactions at 8.25 GeV/ c together with the single particle inclusive cross sections. We present cross sections for prominent resonances occurring in final states K N (nπ) and find the resonance fractions to be roughly independent of multiplicity.

Elastic scattering and two-body annihilations at 5 gev/c

Eide, A. ; Lehmann, P. ; Lundby, A. ; et al.
Nucl.Phys.B 60 (1973) 173-220, 1973.
Inspire Record 83926 DOI 10.17182/hepdata.7885

We present results of measurements of K ± p and p p elastic scattering and of the annihilation reactions p p →π + π − and p p → K + K − at an incident laboratory momentum of 5 GeV/ c . Nearly complete angular distributions were obtained. Results are also presented for π -meson proton elastic scattering in the momentum transfer ranges 2 < − t < 8 (GeV/ c ) 2 (for π + ) and 0.16 < − t < 7 (GeV/ c ) 2 (for π − ). All measurements were done in one experimental geometry. The measured differential cross sections range from 10 to 10 −5 mb/(GeV/ c ) 2 .

LARGE ANGLE HIGH-ENERGY PHOTOPRODUCTION OF SINGLE pi+ MESONS FROM LIQUID HYDROGEN

Anderson, Robert L. ; Gottschalk, B. ; Gustavson, D. ; et al.
Phys.Rev.Lett. 30 (1973) 627, 1973.
Inspire Record 80994 DOI 10.17182/hepdata.3371

We have measured angular distributions for single photoproduced π+ mesons at 4.0-, 5.0-, and 7.5-GeV incident photon energies and at lab angles from 11° to 66° with the Stanford Linear Accelerator Center 8-GeV spectrometer. Combined with previous Stanford Linear Accelerator Center results, this gives complete angular coverages for this range of energies. The data show the usual "t" and "u" diffraction peaks and a "central plateau" region dropping as S−7.3.

Measurement of inclusive photoproduction at 3.2 gev and comparison with electroproduction

Burfeindt, H. ; Buschhorn, G. ; Genzel, H. ; et al.
Phys.Lett.B 43 (1973) 345-348, 1973.
Inspire Record 84913 DOI 10.17182/hepdata.45255

Inclusive photoproduction cross sections for pions, kaons and protons have been measured in the photon fragmentation region and are compared with recent electroproduction data at q 2 = 1.16 (GeV/ c ) 2 . If the cross sections are normalized to the total hadronic cross sections at q 2 = 0 and q 2 = 1.16 (GeV/ c ) 2 , respectively, we observe that more pions, about an equal number of protons, but fewer kaons are found in the photoproduction case for x ≥ 0.3.
