Berlinghieri, J.C. ; Farber, M.S. ; Ferbel, T. ; et al.
Phys.Lett.B 27 (1968) 665-668, 1968.
Inspire Record 1389653 DOI 10.17182/hepdata.29197

In a study of K + p interactions at 12.7 GeV/ c we have carried out a search for meson resonances having any one of the following properties: (a) a strangeness of S =2, (b) S =1 and isotopic spin of I= 3 2 , or (c) S =1, I= 1 2 and decaying into an antihyperon ( Y ) and a nucleon (N).

$K^- + p$ elastic scattering at 3.46 GeV/c

Gordon, J. ;
Phys.Lett. 21 (1966) 117-120, 1966.
Inspire Record 1389617 DOI 10.17182/hepdata.29930

1691 events were fitted to K - p elastic scatters at a K - momentum of 3.46 GeV/ c . The differential cross section as a function of 4 momentum transfer was fitted to exp ( A + Bt + Ct 2 ) with A = 3.7 B = 8.7 ( GeV / c ) −2 and C = 2.0 ( GeV / c ) −4 . The distribution is consistent with zero real part for the forward scattering amplitude.

Annihilations of 5.7 GeV/c $\bar{p}$ in hydrogen into four charged pions

Accensi, A. ; Alles-Borelli, V. ; French, B. ; et al.
Phys.Lett. 20 (1966) 557-559, 1966.
Inspire Record 1389655 DOI 10.17182/hepdata.30034

Annihilations of 5.7 GeV/ c antiprotons in hydrogen into four charged pions have been studied. Production of ϱ o and f o mesons and a possible enhancement in both π ± π ± and π + π − mass distributions at 1.54 GeV is seen. Upper limits for quasi 2-body annihilations are given.

Evidence for vector meson exchange in $\rho^-$ production at 8 GeV/c

Derado, I. ; Poirier, J.A. ; Biswas, N.N. ; et al.
Phys.Lett.B 24 (1967) 112-114, 1967.
Inspire Record 1389618 DOI 10.17182/hepdata.29606

We have studied ϱ − production at 8 GeV / c . The data cannot be explained by one-pion-exchange with absorption and we conclude that vector exchange contributes. This contrasts with ϱ o production at this energy and ϱ − production at lower energy.

$K^- p$ elastic scattering at 2.24 GeV/c

Dickinson, M. ; Miyashita, S. ; Libby, L.Marshall ; et al.
Phys.Lett.B 24 (1967) 596-598, 1967.
Inspire Record 1389623 DOI 10.17182/hepdata.29569

The differential elastic scattering cross section for 2.24 GeV/ c K − p collisions has been measured in film from the Brookhaven 20″ bubble chamber. The total elastic cross section is found to be 6.2 ± 0.7 mb. The exponential dependence on square of the momentum t in (GeV/ c ) 2 is fitted by ( d σ d Ω elastic = (12.4 ± 1.0 mb/sr) exp (7.81 ± 0.25)t . A A fit to a black disc model requires a radius of 0.95 ± 0.05 fm.

The angular distribution of backward elastically scattered pions at 3.55 GeV/c

Baker, W.F. ; Carlson, P.J. ; Chabaud, V. ; et al.
Phys.Lett. 23 (1966) 605-609, 1966.
Inspire Record 1389621 DOI 10.17182/hepdata.29776

The elastic scattering of 3.55 GeV/ c π + and π − mesons by protons was measured at centre-of-mass angles between 165° and 177°. The angular distributions for 864 events show a steeply rising backward peak for π + p, while the shape is less clear for π − p.

Sigma production in p-p collisions at 5 GeV/ c

Sondhi, I. ;
Phys.Lett.B 26 (1968) 645-648, 1968.
Inspire Record 1389658 DOI 10.17182/hepdata.29305

The cross section for the reaction pp → Σ + K + n at 5 GeV/ c is measured to be 48.1 ± 3.5 μ b. The KΣ mass spectrum shows an enhancement at 1.86 GeV, which may due to the Δ (1920) resonance. Adequacy of the one-pion exchange model for the reaction is discussed. The cross section for the reaction pp → Σ + K o p is found to be 24.9 ± 2.3 μ b.

Total cross-section for n-p and n-d scattering at 10 GeV/c neutron momentum

Engler, J. ; Horn, K. ; König, J. ; et al.
Phys.Lett.B 27 (1968) 599-601, 1968.
Inspire Record 1389110 DOI 10.17182/hepdata.752

The total neutron cross-sections were measured with high precision for hydrogen and deuterium. At an average neutron momentum of 10 GeV/c we obtained σ T (np)=39.5±0.5 mb and σ T (nd)=73.3±1.1 mb. These values are in excellent agreement with p-p and p-d total cross sections. No energy dependence was found for n-p cross section between 4 and 10 GeV/c.
