A formation study of n anti-n interactions between 1.09 and 3.45 gev/c. (iv)-features of annihilations into k anti-k and pi mesons

Oh, B.Y. ; Eastman, P.S. ; Ming, Ma.Z. ; et al.
Nucl.Phys.B 63 (1973) 1-27, 1973.
Inspire Record 83880 DOI 10.17182/hepdata.32487

Final state resonance production and single particle momentum spectra are presented for p p annihilations into K K and π's between 1.09 and 3.45 GeV/ c . Resonance production generally agrees with the Lamb statistical model. Momentum spectra of K's and π's are independent of incident energy, while the mean multiplicity increases in proportion to the c.m. energy, supporting the annihilation model of Jacob and Nussinov.

A formation study of n anti-n interactions between 1.51 and 2.90 gev/c. iii. resonance production

Ming, Ma.Z. ; Eastman, P.S. ; Oh, B.Y. ; et al.
Nucl.Phys.B 51 (1973) 77-94, 1973.
Inspire Record 84298 DOI 10.17182/hepdata.32684

A systematic study of p p and p d resonance production cross sections in non-strange annihilation channels between 1.51 and 2.90 GeV/ c has been completed. The data have been analysed in relation to the three known structures at c.m. N N energies of 2190, 2350 and 2375 MeV. Several resonance intermediate states may have broad maxima near the isopin one 2350 MeV structure. However, more data below 1.6 GeV/ c are required to better describe the background in this region before firm conclusions may be drawn.

A formation study of n anti-n interactions between 1.51 and 2.90 gev/c. i. topological and reaction cross-sections

Eastman, P.S. ; Ming, Ma.Z. ; Oh, B.Y. ; et al.
Nucl.Phys.B 51 (1973) 29-56, 1973.
Inspire Record 84299 DOI 10.17182/hepdata.32706

A systematic study of p p and p d topological and reaction cross sections between 1.51 and 2.90 GeV/ c has been completed. The data have been analysed in relation to the three known structures at c.m. N N energies of 2190, 2350 and 2375 MeV. The data suggest that four- and six-pion annihilations of antiprotons on neutrons may be the source of the 2350 MeV effect. Further data below 1.60 GeV/ c are required to verify this tentative conclusion.

Pi- p elastic scattering near 180 degrees between 600 and 1280 mev/c

Crabb, D.G. ; Keller, R. ; O' Fallon, J.R. ; et al.
Phys.Rev.Lett. 27 (1971) 216-219, 1971.
Inspire Record 68952 DOI 10.17182/hepdata.21460

The differential cross sections for π−p elastic scattering over the angular range 155° to 177° in the center of mass have been measured at 33 incident-pion momenta in the range 600 to 1280 MeV/c. Angular distributions are presented. The extrapolated differential cross sections at 180° show considerable structure, in particular a dip near 1150 MeV/c. In general the near-180° cross sections do not agree with existing phase shift solutions above 1000 MeV/c

Total cross-sections of K+- mesons and anti-protons on nucleons up to 3.3-GeV/c

Abrams, R.J. ; Cool, R.L. ; Giacomelli, G. ; et al.
Phys.Rev.D 1 (1970) 1917-1935, 1970.
Inspire Record 55141 DOI 10.17182/hepdata.25091

Total cross sections of K± and p¯ on hydrogen and deuterium were measured in a standard transmission experiment with statistical precisions of the order of 0.05-0.25%. Data were obtained in the momentum range 2.45-3.30 GeV/c for K−N, 1.55-3.30 GeV/c for K+N, and 1.00-3.30 GeV/c for p¯N. Cross sections for the pure isotopic spin states are obtained using a procedure for the deuterium data which takes into account Fermi motion and the shadow effect. Evidence for the following new structures was found: Y1*(2455), Y1*(2620), Y0*(2585), Z1*(2150), Z1*(2500), π1*(2290), π1*(2350), and π0*(2375).

Nucleon-Nucleon Total Cross Sections from 1.1 to 8 GeV/c

Bugg, D.V. ; Salter, D.C. ; Stafford, G.H. ; et al.
Phys.Rev. 146 (1966) 980-992, 1966.
Inspire Record 50610 DOI 10.17182/hepdata.408

Measurements have been made of the total cross sections σ(p−p) and σ(p−d) over the laboratory momentum range 1.1 to 8 GeV/c, with relative errors of 0.1%. The absolute accuracies of these cross sections are limited to 0.3% by lack of information which will allow the Coulomb-nuclear interference to be calculated accurately. Values of the total cross sections σ(p−n) and σ(I=0) are deduced by assuming the Glauber correction. Structure is observed in σ(p−p) near a mass value of 2.75 GeV/c2; its interpretation is discussed. σ(I=0) rises rapidly in the range 2.3 to 2.9 GeV/c2, and this is attributed to the onset of strong inelastic scattering.
