HIGH-ENERGY DIFFRACTION DISSOCIATION OF K0(L) INTO EXCLUSIVE FINAL STATES

Lamm, M.J. ; Wiss, J.E. ; Avery, P. ; et al.
Phys.Rev.D 36 (1987) 3341-3352, 1987.
Inspire Record 244943 DOI 10.17182/hepdata.23353

We have observed diffraction dissociation of KL0 mesons with a carbon target into the exclusive final states KS0π+π−, KS0ω, and KS0φ. The diffraction production cross section for these states is not strongly dependent on the incident energy, varying at most by 30% between 75 and 150 GeV. The mass distributions do not change appreciably as a function of laboratory energy. The ratio of the diffractive mass-threshold production of K*±π∓, KS0ρ, KS0ω, and KS0φ is compared with previously obtained lower-energy data.

Measurement of Anti-proton - Proton Small Angle Elastic Scattering at Low Momentum

Linssen, L. ; Beard, C.I. ; Birsa, R. ; et al.
Nucl.Phys.A 469 (1987) 726, 1987.
Inspire Record 245092 DOI 10.17182/hepdata.37014

Two high statistics measurements of antiproton-proton small-angle elastic scattering, at p = 233 MeV/ c and p = 272 MeV/ c , are presented. The measurements were carried out at the LEAR facility at CERN. By the Coulomb-nuclear interference method, values are obtained for the real-to-imaginary ratio ρ of the p̄p forward nuclear scattering amplitude and for its exponential slope b : ρ = + 0.041 ± 0.026 and b = 71.5 ± 4.5 (GeV/ c ) −2 at 233 MeV/ c and ρ = −0.014 ± 0.027 and b = 47.7 ± 2.7 (GeV/ c ) −2 at 272 MeV/ c . The method to derive these values is discussed in detail and so are the uncertainties contributing to their systematic error. The results are compared with predictions from forward dispersion relation calculations and with predictions from p̄p potential models.

Study of Elastic $\pi^+ p$, $K^+ p$ and $p p$ Scattering at 250-{GeV}/$c$

The NA22 collaboration Adamus, M. ; Ajinenko, I.V. ; Agababyan, N.M. ; et al.
Phys.Lett.B 186 (1987) 223-226, 1987.
Inspire Record 246909 DOI 10.17182/hepdata.40833

Results are presented on π + p and K + p elastic scattering at 250 GeV/ c , the highest momentum so far reached for positive meson beams. The experiment (NA22) was performed with the european hybrid spectrometer. The π + p elastic cross section stays constant with energy while the K + p cross section increases.

The Cross-section of Diffraction Dissociation at the {CERN} {SPS} Collider

The UA4 collaboration Bernard, Denis ; Bozzo, M. ; Braccini, P.L. ; et al.
Phys.Lett.B 186 (1987) 227-232, 1987.
Inspire Record 235895 DOI 10.17182/hepdata.30212

Single diffraction dissociation was measured in the reaction p¯p→p¯X at the centre-of-mass energy √ s = 546 GeV. The mass M of the system X was deduced from the pseudorapidity distribution of the observed charged tracks. The cross section of single diffraction dissociation for M 2 /s⩽0.05isσ sd =9.4 ± 0.7 mb. Comparison to the ISR data shows that σ sd increases with energy less fast than the total and the elastic cross sections.
