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).

Measurements of the Total Cross-sections of $\Sigma^-$ and $\Xi^-$ on Protons and Deuterons Between 74-{GeV}/$c$ and 137-{GeV}/$c$

The Σ − p and Σ − d total cross sections have been measured to a statistical accuracy of ±1% and ±0.5%, respectively, at five momenta from 74.5 to 136.9 GeV/ c , using the hyperon beam at the CERN SPS. The Ξ − p and Ξ − d total cross sections have also been measured to the same statistical accuracy at 101.5 and 133.8 GeV/ c . The systematic uncertainty at each momentum is estimated to be of the order of ±0.5%. The hyperon-nucleon cross sections are shown to be rising with energy, and the data are compared with various phenomenological models.

Observation of Structure in anti-p p and anti-p d Total Cross-Sections Below 1.1-GeV/c

Carroll, A.S. ; Chiang, I.-H. ; Kycia, T.F. ; et al.

Phys.Rev.Lett. 32 (1974) 247, 1974.

Inspire Record 567 DOI 10.17182/hepdata.21309

Total cross sections of p¯p and p¯d have been measured between 360 and 1050 MeV/c, with high statistical precision. Structures are observed in both cross sections at about the same momenta. For p¯p, the central mass is 1932±2 MeV/c2, and a fit to the data with a simple Breit-Wigner resonance plus background gives Γ=9−3+4 MeV/c2. The data suggest that the structures are in the isospin-1 state.

About 45000 interactions of antiprotons of kinetic energy between 57 and 170 MeV have been measured in a deuterium bubble chamber. Total and annihilation cross-sections have been determined at 9 values of the antiproton energy together with the differential crosssection dσ/dt for scattering events. In spite of the peculiar behaviour of the deuteron target at these low energies a reliable measure of the antiproton-neutron annihilation cross-section has been obtained.

TOTAL AND PARTIAL ANTI-P D CROSS-SECTIONS FROM 0.26-GEV/C TO 0.47-GEV/C

The p¯d total cross section is ∼10% larger than the A+BP extrapolated cross section seen at higher (∼0.5-2.0 GeV/c) momenta. The excess is mainly due to the nonannihilation part of the total cross section. The p¯d annihilation cross sections in H2 and D2 are the same. These observations are consistent with known properties of the N¯N(1897). A 3σ dip is present at ∼0.43 GeV/c mainly due to pp¯ annihilation. This dip cannot be understood in terms of a single resonance at N¯N(1897) and the S(1935). Our cross sections are ∼10-20% higher than the recent measurements of Hamilton et al.

SEARCH FOR THE S MESON

Total and annihilation cross sections for p¯p and p¯d have been measured over the momentum range 355-1066 MeV/c at closely spaced momenta and with good energy resolution. No evidence is seen for the narrow structure reported by other experiments in the vicinity of 500 MeV/c. The present measurements indicate a broader enhancement in this region, which, if interpreted as a resonance, would have a height of ∼ 3 mb and a width of ∼ 20 MeV. This structure appears only in the p¯p data.

d ̄ p and p ̄ d total cross-sections have been measured at 13.3 and 6.65 GeV/ c respectively to check CPT-invariance. The standard transmission technique was used. The difference of d ̄ p and p ̄ d total cross-sections appeared to be equal 0.2 ± 2.6 mb. In addition d ̄ d and p ̄ p total cross-sections have been obtained. The experimental data allowed us to derive the total cross-section of antineutrons on protons, neutrons and deutrons.
