Anti-Proton-Proton Annihilation Into pi+ pi- and K+ K- at 6.2-GeV/c

Buran, T. ; Eide, A. ; Helgaker, P. ; et al.
Nucl.Phys.B 116 (1976) 51-64, 1976.
Inspire Record 110027 DOI 10.17182/hepdata.35565

The angular distributions for the two annihilation channels p ̄ p →π + π − and p ̄ p → K + K − have been measured at 6.2 GeV/ c . The two-pion channel shows peripheral peaks for π + and π − going forward, and the two-kaon channel shows a peripheral peak for the K − going forward. The results have been compared with the line-reversed elastic backward scattering reactions and also with a constituent interchange model.

Nucl.Phys.B 116 (1976) 77-98, 1976.
Inspire Record 110113 DOI 10.17182/hepdata.35634

The inclusive production of low-momentum charged pions, kaons, and protons has been measured at x = 0 over the ISR energy range 23 < √ s < 63 GeV. The average increase in the invariant differential cross section is 36 ± 2% for π + , 41 ± 2% for π − , 52 ± 8% for K + , 69 ± 8% for K − , 8 ± 5% for p, and 84 ± for p ̄ . Pions have been measured in the range 0.04 < p T < 0.4 GeV/ c , kaons over 0.1 < p T < 0.3 GeV/ c , and nucleons over 0.1 < p T < 0.5 GeV/ c .

First Results on Diffraction Dissociation of Neutrons at the ISR

Mantovani, G.C. ; Cavalli-Sforza, M. ; Conta, C. ; et al.
Phys.Lett.B 64 (1976) 471-474, 1976.
Inspire Record 110024 DOI 10.17182/hepdata.27617

Neutron diffraction dissociation has been measured at the ISR in proton-neutron interactions at 37 GeV c.m. energy. The data were taken with the Split Field Magnet detector, during a short deuteron storage test run with colliding p-d beams. Differential mass and momentum transfer distributions are reported; the value of the total cross-section shows a weak s -dependence when compared to lower energy data.

Neutron Fragmentation and Inclusive Charge Exchange in p d and pi+ d Interactions at 195-GeV/c

Eisenberg, Y. ; Haber, B. ; Hochman, D. ; et al.
Phys.Rev.Lett. 38 (1977) 108, 1977.
Inspire Record 109610 DOI 10.17182/hepdata.21024

An excess of negative particles and depletion of positive particles in the backward hemisphere (c.m. system) is observed in π+ and p interactions on neutron target. dσ−dy is compared with pp interactions and the difference is related to the slow-proton spectrum produced in the pn interactions. A neutron fragmentation component is observed and the inclusive charge-exchange probability at the nucleon vertex is found to be about 0.4.

Measurement of the Magnetic Structure Function of the Deuteron at q**2 = 1.0-(GeV/c)**2

Martin, F. ; Arnold, R.G. ; Chertok, B.T. ; et al.
Phys.Rev.Lett. 38 (1977) 1320, 1977.
Inspire Record 109585 DOI 10.17182/hepdata.21023

At a square of the momentum transfer of 1.0 (GeV/c)2 the elastic scattering of electrons on deuterons has been measured at electron scattering angles of 8°, 60°, and 82°. From these data we have extracted a value of B(q2)=(0.59±1.20)×10−5 for the deuteron. This measurements extends the range in momentum transfer by almost a factor of 2 over the previous measurements.

Eta and omega Meson Production in Medium-Energy pi+- p and K- p Interactions

The Aachen-Berlin-Bonn-CERN-Cracow-London-Vienna-Warsaw collaboration Bartke, J. ; Kirk, H. ; Kaltwasser, J. ; et al.
Nucl.Phys.B 118 (1977) 360-370, 1977.
Inspire Record 110525 DOI 10.17182/hepdata.48967

The production of η(550) and ω(780) mesons is studied in π ± p interactions at 16 GeV/ c and K − p interactions at 10 and 16 GeV/ c . Cross sections for exclusive channels are presented, and for the π + p data differential cross sections are given for quasi-inclusive production where the η or ω is required to be accompanied by charged particles only. Close similarities are observed between η, ω and also ϱ 0 (770) production in terms of longitudinal and transverse variables. By a rough estimate, the η, ω and ϱ 0 inclusive yields are found to be in the ratio 0.32 : 0.85 : 1, respectively, for 16 GeV/ c π + p collisions. For non-peripheral production we estimate this same ratio to be 0.34 : 0.9 : 1.

Inspire Record 945158 DOI 10.17182/hepdata.21039

Polarization in π−p elastic scattering, with emphasis in the region around the secondary dip and also θc.m.=90°, has been measured at 2.93 and 3.25 GeV/c. We observe an interesting sign change in this angular region.

Pi- p Interactions at 360-GeV/c: Measurement of the Total and Elastic Cross-Sections and the Charged Particle Multiplicity Distribution

Firestone, A. ; Anderson, E.W. ; Chang, V. ; et al.
Phys.Rev.D 14 (1976) 2902, 1976.
Inspire Record 3926 DOI 10.17182/hepdata.24670

In a sample of 108 563 pictures taken with the Fermilab 30-inch hydrogen bubble chamber, exposed to a 360-GeV/c π− beam, we have observed 19 453 interactions in a selected fiducial region. The observed charged multiplicity distribution has been corrected for the effects of scan efficiency, errors in prong count, missed close-in vees, secondary interactions, and neutron stars and for Dalitz pairs. The two-prong events have been corrected for losses at low −t. The total cross section is measured to be 25.25 ± 0.35 mb, and the elastic cross section is 3.61 ± 0.11 mb with an exponential slope of (8.82 ± 0.30) (GeV/c)−2. The average charged-particle multiplicity for inelastic events is 8.73 ± 0.04, and the second moment f2 is measured to be 9.83 ± 0.23.

Study of A2- --> eta pi- in the Reaction pi- p --> pi- pi- pi+ pi0 p at 11.2-GeV/c

Inspire Record 109786 DOI 10.17182/hepdata.37635

The analysis of A2−→ηπ− at 11.2 GeV/c confirms that A2− is essentially produced by natural-parity exchange. In the differential cross-section as a function oft′ there is evidence of the dip at smallt′ values. The branching ratio (A2→ηπ)/(A2→ϱπ) is 0.18±0.05.
