Antiproton-Proton Cross Sections at 1.0, 1.25, and 2.0 Bev

Armenteros, Rafael ; Coombes, Charles A. ; Cork, Bruce ; et al.

The interaction of 1.0-, 1.25-, and 2.0-Bev antiprotons with protons has been studied with the aid of a 4π solid-angle scintillation-counter detector system. The measured total cross sections at the above energies are 100, 89, and 80 mb, respectively. At each energy, the charge-exchange cross section is approximately 5 mb. The total elastic cross sections are 33, 28, and 25 mb, respectively, at the three energies. The angular distribution of elastic scattering has been fitted with a simple optical-model calculation.

Absence of discrete s-channel resonances in anti-p p interactions at intermediate energies

Fields, T. ; Cooper, W.A. ; Rhines, D.S. ; et al.
Phys.Rev.Lett. 27 (1971) 1749-1752, 1971.
Inspire Record 75556 DOI 10.17182/hepdata.21475

We give new experimental results on ρω interference and two-body cross sections in p¯p annihilation at 2.3GeVc. These are used, together with ρω interference results from lower energies, to argue that the annihilation process is not mediated by discrete s-channel mesonic resonances in the mass range 2.1-2.6 GeV.

Comparison of new data on anti-p p --> pi- pi+ and other two meson states at 2.3-gev/c

Fields, T. ; Cooper, W.A. ; Rhines, D.S. ; et al.
Phys.Lett.B 40 (1972) 503-506, 1972.
Inspire Record 75681 DOI 10.17182/hepdata.28267

Complete angular distributions for the reactions p p → π − π + and other two meson states at 2.3 GeV/ c are presented. The extraordinary π − π + angular distribution is contrasted with the other final states and the predictions of simple models. A favourable comparison is made with the qualitative features of a dual model involving high mass meson states with a strong degeneracy with respect to I -spin.

Neutral associated production by 8, 10.7 and 15.7 gev/c pi- incident on protons

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.
Phys.Rev.D 8 (1973) 27-38, 1973.
Inspire Record 81979 DOI 10.17182/hepdata.22059

We present differential and total cross sections for two reactions: π−p→K0Λ and π−p→K0Σ0. The incident pion momenta were 8, 10.7, and 15.7 GeVc. The results are based on an analysis of approximately 22 600 events of the two reactions where the π+ and π− from the decay of the KS0 were detected in the forward leg of the Double Vee Magnetic Spectrometer. The separation of Λ recoils from Σ0 recoils was accomplished by the missing-mass technique.

Elastic anti-p d scattering at 5.55 gev/c incident momentum

Braun, Henri ; Fridman, A. ; Jegham, E. ; et al.
Nucl.Phys.B 54 (1973) 61-77, 1973.
Inspire Record 84177 DOI 10.17182/hepdata.32581

Based on 150 000 photographs taken at the ZGS with the 30 inch deuterium-filled chamber we present an analysis of the elastic p d scattering reaction. Due to unrecoreded small deuteron recoils we were only able to measure the elastic cross section in the four-momentum region | t | > 0.03 (GeV/ c ) 2 . Extrapolation towards small | t | by two different methods gave us two compatible estimates of the total elastic cross section. The differential cross section was analyzed by means of the Glauber formalism both with and without the effects due to the D-wave part of the deuteron wave function. The differential cross sections of np at 5.4 GeV/ c and pn deduced from our data were compared and exhibit a crossover phenomenon.

ANTI-PROTON - PROTON ANNIHILATION INTO FIVE AND MORE PIONS AT 2.32-GeV/c

Oren, Y. ; Cooper, W.A. ; Fields, T. ; et al.
Nucl.Phys.B 71 (1974) 189-210, 1974.
Inspire Record 80613 DOI 10.17182/hepdata.32346

High statistics data on p p annihilation into five and more pions at 2.32 GeV/ c are presented. Cross sections for various final states and for the production of meson resonances have been determined. The Dalitz plot asymmetry for some 4 800 ω decay events produced in p p → 2π + 2π − π 0 is found to be consistent with zero. Upper limits for the production of exotic meson resonances are presented.
