Resonance production and clustering effects in reactions $K^− p \to \Lambda^0$ + pions at an incident beam momentum 8.25 GeV/c

The Athens-Demokritos-Liverpool-Vienna collaboration Michaelidou, Ch. ; Kakoulidou, M. ; Michaelides, P. ; et al.
Nucl.Phys.B 140 (1978) 249-270, 1978.
Inspire Record 1392685 DOI 10.17182/hepdata.35024

We have estimated cross sections for the production of resonances in the reactions K − p → Λ 0 + pions. The data have also been analysed by a method which examines event-to-event fluctuations. Within the framework of the simple parametrization of resonance production assumed, the contribution from the resonances is insufficient to explain the observed fluctuations in the longitudinal emission of the final-state particles. These features are well reproduced by an independent cluster emission model.

Diffraction-like structure in elastic proton-proton scattering at large momentum transfers

Allaby, J.V. ; Diddens, A.N. ; Klovning, A. ; et al.
Phys.Lett.B 27 (1968) 49-53, 1968.
Inspire Record 1392696 DOI 10.17182/hepdata.29184

Measurements of wide angle elastic p-p scattering between 7 and 12 GeV/c are reported. Structure found in the angular distributions is suggestive of diffraction.

Discontinuous behaviour in large angle proton-proton elastic scattering at high energies

Allaby, J.V. ; Cocconi, G. ; Diddens, A.N. ; et al.
Phys.Lett.B 25 (1967) 156-159, 1967.
Inspire Record 1389227 DOI 10.17182/hepdata.754

Measurements of elastic proton-proton differential cross sections for angles between 65° and 90° c.m.s. have been made at 8, 9, 10, 11, 14, 15 and 21 GeV/c. The shape of the angular distribution is found to change suddenly between 8 and 11 GeV/c. An interpretation of this discontinuous behaviour in terms of the reactive effects of baryon-antibaryon pair production is proposed.

Backward π p elastic scattering at 2.85 and 3.30 GeV/c

Baker, W.F. ; Carlson, P.J. ; Chabaud, V. ; et al.
Phys.Lett.B 25 (1967) 361-364, 1967.
Inspire Record 1389663 DOI 10.17182/hepdata.29442

Backward elastic scattering has been measured for π + p at 2.85 and 3.30 GeV/ c and for π − p at 3.30 GeV/ c . The π + p angular distributions show steep backward peaks, whereas the π − p distribution is flatter. At 2.85 GeV/ c the π + p differential cross section close to 180° is more than twice that at 3.30 GeV/ c , supporting the assignment J P = 11 2 + for Δ δ (2420) resonance. The π + p data at 2.85 GeV/ c indicate the onset of a dip at cos θ c.m. ≈ −0.97.

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.

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.
