Inelastic Diffractive Scattering at FNAL Energies

Ayres, D.S. ; Diebold, Robert E. ; Cutts, D. ; et al.
Phys.Rev.Lett. 37 (1976) 1724, 1976.
Inspire Record 109174 DOI 10.17182/hepdata.21057

Inelastic differential cross sections have been measured for π±p, K±p, and p±p at 140- and 175-GeV/c incident momentum over a |t| range from 0.05 to 0.6 GeV2 and covering a missing-mass region from 2.4 to 9 GeV2. For Mx2 greater than 4 GeV2, the invariant quantity Mx2d2σdtdMx2 was found to be independent of Mx2 at fixed t and could be adequately described by a simple triple-Pomeron form. The values obtained for the triple-Pomeron couplings are identical within statistics for all channels.

Resonance Production in the Reaction K+ p --> K0 p pi+ at 5-GeV/c, 8.25-GeV/c and 16-GeV/c

Colley, D.C. ; Carney, J.N. ; James, M.F. ; et al.
Nucl.Phys.B 110 (1976) 333-354, 1976.
Inspire Record 108770 DOI 10.17182/hepdata.35742

We present a systematic analysis of the production of K ∗+ (892) and Δ ++ (1236) resonances in the K + p → K 0 p π + reaction at 5, 8.25 and 16 GeV/ c . We have measured total cross sections, differential cross sections, density matrix elements and examined resonance production mechanisms in terms of the exchange of states with definite naturality. Some results on the reaction K + p → K ∗+ (1420) p are also given.

Elastic Scattering Crossovers from 50-GeV to 175-GeV

The Fermilab Single Arm Spectrometer Group collaboration Anderson, R.L. ; Anelli, E.F. ; Ayres, D.S. ; et al.
Phys.Rev.Lett. 37 (1976) 1025, 1976.
Inspire Record 108810 DOI 10.17182/hepdata.21092

A comparison of K±p and p±p elastic scattering is made for incident energy 50 to 175 GeV. Average values of 0.19±0.04 and 0.11±0.02 GeV2 were found for the invariant-momentum-transfer values of the Kp and pp crossover points, respectively.

Comparison of n --> n + pi, n + pi + pi and Lambda + K Diffractive Excitation Systems at 14.3-GeV/c and 500-GeV/c-1500-GeV/c

Denegri, D. ; Pons, Y. ; Laffaille, J.M. ; et al.
Nucl.Phys.B 114 (1976) 413-436, 1976.
Inspire Record 109084 DOI 10.17182/hepdata.35706

We compare some aspects of the N→N π , N→N ππ and N → Λ K diffractive fragmentation systems induced by 14.3 GeV/ c incident K − mesons with those obtained in pp interactions at ISR energies. The similarity between the low-mass Nπ and Nππ systems produced by different incident particles at c.m. energies differing by an order of magnitude is very striking. The shapesof the mass spectra (not the M 2 / s spectra) are approximately independent of s , both in the resonant and non-resonant diffractive dissociation components. These findings, as well as features of the differential cross sections and decay angular distributions, indicate that the (asymptotic) diffractive dynamics operative at ISR energies is already dominant at 10–20 GeV/ c , remains essentially unchanged over this broad energy range, and has approximate vertex factorization properties.

Measurement of the Polarization in Backward Angle pi- p Elastic Scattering at 2.93-GeV/c and 3.25-GeV/c

Auer, P. ; Bridges, D. ; Droege, T. ; et al.
Nucl.Phys.B 113 (1976) 279-284, 1976.
Inspire Record 3320 DOI 10.17182/hepdata.35605

Polarization in π − p elastic scattering, with emphasis over the backward region, has been measured at 2.93 and 3.25 GeV/ c . We observe large changes in polarization compared with existing data above and below these energies. Our data may be useful in determining the properties of resonances and in understanding baryon exchanges.
