Pi- photoproduction from deuterium at laboratory energies 600 to 1250 mev

Scheffler, P.E. ; Walden, P.L. ;
Phys.Rev.Lett. 24 (1970) 952-954, 1970.
Inspire Record 62962 DOI 10.17182/hepdata.32219

The differential cross section for the reaction γ+n→π−+p was measured for laboratory photon energies between 600 and 1250 MeV, using a liquid deuterium target. The internal nucleon momentum distribution of the deuteron was used to calculate the major effect of using deuterium as a neutron target. The data show that the amplitude to excite the F15(1688) resonance is small, in agreement with a recent quark-model prediction.

Study of k- pi- scattering using the reaction k- d ---> k- pi- p p(s)

Cho, Y. ; Derrick, M. ; Johnson, D. ; et al.
Phys.Lett.B 32 (1970) 409-412, 1970.
Inspire Record 63111 DOI 10.17182/hepdata.28719

Approximately 700 events of the reaction K − d → K − π − pp s produced by 5.5 GeV/ c kaons were used to measure the cross section for Kπ elastic scattering in the T = 3 2 state by a Chew-Low extrapolation. The cross section does not exceed 2.1 mb and has no structure for Kπ masses from threshold up to 2.0 GeV.

Search for exotic resonances in k- d interactions at 3 gev/c

The SABRE collaboration Giacomelli, G. ; Lugaresi-Serra, P. ; Minguzzi-Ranzi, A. ; et al.
Phys.Lett.B 33 (1970) 373-376, 1970.
Inspire Record 63055 DOI 10.17182/hepdata.28726

A systematic search for exotic states produced in K − d interactions at 3 GeV/ c is reported. From the analysis of the mass spectra of strange mesons, non-strange mesons, hyperons with S = −1 and S = −2, upper limits for the production cross sections of exotic resonances may be placed at one or two orders of magnitude smaller than for the production of normal resonances of same strangeness and baryon number.

Elastic scattering of protons on deuterons at high energy

Bradamante, F. ; Fidecaro, G. ; Fidecaro, M. ; et al.
Phys.Lett.B 32 (1970) 303-308, 1970.
Inspire Record 63124 DOI 10.17182/hepdata.28773

The differential cross-section for pd elastic scattering has been measured at 9.7, 12.8 and 15.8 GeV/ c for t -values up to −2 GeV 2 . The Glauber multiple scattering model has been used to analyse the data, the main interest being the double scattering region.

Measurements of the polarisation of the recoil proton in elastic electron proton scattering at q-squared=1.3, 1.5 and 1.9(gev/c)squared

Kirkman, H.C. ; Railton, R. ; Rutherglen, J.G. ; et al.
Phys.Lett.B 32 (1970) 519-522, 1970.
Inspire Record 63101 DOI 10.17182/hepdata.28765

An experiment has been carried out to determine the imaginary part of the two-photon exchange amplitude by measuring the polarisation of the recoil proton in elastic electron-proton scattering. The polirisation was found to be −0.006 ± 0.030 at q 2 = 1.3 (GeV/ c ) 2 , +0.052 ± 0.55 at 1.5 (GeV/ c ) 2 and +0.065 ± 0.087 at 1.9 (GeV/ c ) 2 .

Measurement of proton Compton scattering at 6 gev and small momentum transfers

Buschhorn, G. ; Criegee, L. ; Dubal, L. ; et al.
Phys.Lett.B 33 (1970) 241-244, 1970.
Inspire Record 63064 DOI 10.17182/hepdata.28544

Compton scattering on protons has been measured at a mean photon energy of 6 GeV and four-momentum transfers − t between 0.06 and 0.60 (GeV/ c ) 2 . The differential cross section shows a diffraction-like behaviour. The cross section extrapolated to t =0 is in fair agreement with the optical point. Discrepancies with the vector meson dominance model are pointed out.

Single photoproduction of eta-mesons on hydrogen in the forward direction at 4 and 6 gev

Inspire Record 63065 DOI 10.17182/hepdata.28543

The differential cross-section of the reaction γ p→ η p has been measured at the Deutsches Elektronen Synchrotron (DESY) at mean photon energies of 4 and 6 GeV in the momentum transfer range between zero and 1.4 GeV 2 . The data show a slight maximum around t =−0.15 GeV 2 and fall off smoothly till t =−1.4 GeV 2 . There is no indication of a dip around t =−0.5 GeV 2 .
