Pion and Nucleon Dissociation in $\pi^- p \to \pi^- \pi^+ \pi^- p$ at 205 GeV/c

Bingham, H.H. ; Chew, D.M. ; Fretter, W.B. ; et al.
Phys.Lett.B 51 (1974) 397-401, 1974.
Inspire Record 90046 DOI 10.17182/hepdata.27930

In a 48 000-picture exposure of the Fermilab 30-inch hydrogen bubble chamber to a 205 GeV/ c π − beam, we have measured 169 events of the reaction, π − p → π − π + π − p, with a cross section of 635 ± 61 μ b. This reaction proceeds almost entirely via low mass π − → 3 π and p → p ππ dissociation. Factorization is satisfied for p → pππ dissociation in πp and pp interactions.

Inclusive rho0 Production in pi- p Interactions at 205-GeV/c

Winkelmann, F.C. ; Bingham, H.H. ; Chew, D.M. ; et al.
Phys.Lett.B 56 (1975) 101-104, 1975.
Inspire Record 91206 DOI 10.17182/hepdata.27880

The inclusive ϱ ° production cross section has been measured in the reaction π − p → π + π − X at 205 GeV/ c . We find σ ( ϱ ° ) = 13.5 ± 3.4 mb, with most of the production occuring in the central region. Assuming σ ( ϱ + ) ≈ σ ( ϱ − ) ≈ σ ( ϱ ° ), it is concluded that approximately one-third of the pions at this energy come from ϱ -decay.

Neutron-Proton Elastic Scattering from 10-GeV/c to 70-GeV/c

Bohmer, V. ; Engler, J. ; Flauger, W. ; et al.
Nucl.Phys.B 91 (1975) 266-278, 1975.
Inspire Record 98395 DOI 10.17182/hepdata.32033

The neutron-proton elastic differential cross section has been measured for incident momenta between 10 and 70 GeV/c and for values of the momentum transfer squared between 0.1 and 2.8 (GeV/c) 2 . The forward peak and the break at about ∣ t ∣ = 1 (GeV/ c ) 2 are very similar to corresponding pp data.

Inclusive and Semiinclusive $\rho^0$ Production in $\pi^- p$ Interactions at 147-GeV/c.

Fong, D. ; Heller, M. ; Shapiro, A.M. ; et al.
Phys.Lett.B 60 (1975) 124-128, 1975.
Inspire Record 102526 DOI 10.17182/hepdata.27734

We present data on inclusive and semi-inclusive ϱ 0 production in 147 GeV/ c π − p interactions. We find a total cross section of 7.3 ± 1.3 mb. Most of this cross section is found in the lower topology events (⩽ 10 prongs), and in the central and forward rapidity regions. The P T 2 dependence of ϱ 0 production, 〈: n > ϱ 0 per event, and the ϱ 0 / π + ratios are also discussed.

Study of the Energy and Charged Multiplicity Dependence of Inclusive pi- Production in pi- p Interactions Up to Fermilab Energies

Morris, W. ; Oh, B.Y. ; Parker, D.L. ; et al.
Phys.Lett.B 56 (1975) 395-399, 1975.
Inspire Record 2113 DOI 10.17182/hepdata.27878

Using new data from 100 GeV c π − interactions, we find the energy dependence of the invariant cross-section in the target fragmentation (central) region to be consistent with an A + Bs − 1 2 (C + Ds − 1 4 ) behavior. The leading particle peak near x = + 1 exhibits a width in x which becomes smaller with increasing energy and an integrated cross section which is approximately energy independent.

Charged-Particle Multiplicities in 100-GeV/c anti-p p Interactions

Ansorge, R.E. ; Bust, C.P. ; Carter, J.R. ; et al.
Phys.Lett.B 59 (1975) 299-302, 1975.
Inspire Record 2603 DOI 10.17182/hepdata.27765

Results are presented on the topological cross sections obtained for antiproton-proton interactions from an exposure of the Fermilab 30-inch bubble chamber to a 100 GeV/ c negative beam enriched in p 's. The p p inelastic cross section is found to be σ inel = 34.6 ± 0.4 mb, and the average inelastic charged particle multiplicity to be 〈 n 〉 = 6.74 ± 0.05.

Neutron-Proton Charge-Exchange Scattering from 22-GeV/c to 65-GeV/c

Babaev, A. ; Brachman, E. ; Eliseev, G. ; et al.
Nucl.Phys.B 110 (1976) 189-204, 1976.
Inspire Record 100178 DOI 10.17182/hepdata.35776

The differential cross sections for neutron-proton elastic charge-exchange scattering have been measured with a two-arm technique for incident neutron momenta between 22 and 65 GeV/ c and for values of the momentum transfer squared between 0.002 and 0.8 (GeV/ c ) 2 . The sharp forward peak observed previously at lower energies is also present at momenta up to 65 GeV/ c ; however the s dependence of the cross section is slowing down.

Two Particle Correlations in Inclusive and Semiinclusive pi- p Reactions at 200-GeV/c

Biswas, N.N. ; Bishop, J.M. ; Cason, N.M. ; et al.
Phys.Rev.Lett. 35 (1975) 1059, 1975.
Inspire Record 2906 DOI 10.17182/hepdata.3351

Significant two-particle correlations of dynamical origin are observed in 200 GeV/c π−p inclusive interactions. This is demonstrated by comparison with kinematic correlations calculated from an independent-particle-emission model. Two distinct correlation types are observed: (a) unlike-particle correlations with correlation length ∼ 1.3 rapidity units independent of azimuthal separation, and (b) like-particle correlations with correlation length ∼ 0.4 rapidity units which are observed only for small azimuthal separations.
