Comparison of the Differential Cross-sections for $\pi^- p \to \eta^\prime n$ and $\pi^- p \to \eta n$ at 8.45-{GeV}/$c$

Stanton, N.R. ; Edwards, K.W. ; Legacey, D. ; et al.
Phys.Lett.B 92 (1980) 353-357, 1980.
Inspire Record 8522 DOI 10.17182/hepdata.27193

The ratio R of the differential cross sections for π - p→ η ′n and π - p → η n has been measured with high statistics and small systematic errors at 8.45 GeV/ c . R is generally interpreted as the relative content of nonstrange, ground-state quarks in η' and η. We find that R decreases with increasing ⋎ t ⋎; however, extrapolation to t =0 gives R (0) = 0.672 ± 0.032 (statistical) ± 0.47 (systematic) for the dominant spin flip cross sections, and R (0) = 0.500 ± 0.035 for the spin non-flip, in excellent agreement with results at higher energy. An improved value of the branching fraction ( η '→ γγ )/( η '→all) of 0.0200 ± 0.0018 is obtained.

Measurement of $\omega$ Meson Photoproduction on Protons From 46 GeV to 180 GeV

Egloff, R.M. ; Davis, P.J. ; Luste, G.J. ; et al.
Phys.Rev.Lett. 43 (1979) 1545, 1979.
Inspire Record 142364 DOI 10.17182/hepdata.3122

Elastic ω-meson photoproduction on protons has been measured from 46 to 180 GeV. The cross section is approximately constant with photon energy and averages 1.10 ± 0.08 μb. The t dependence of the differential cross section is consistent with A exp(bt), where b=8.4±0.7 GeV−2. The photon-omega coupling constant, obtained from a normalization of hadron elastic-scattering cross sections to the photoproduction data of this experiment (with use of vector-meson dominance and an additive quark model), is γω24π=5.4±0.4.

Elastic Scattering of pi-, K-, and anti-p from Hydrogen at 8-GeV/c and 16-GeV/c

Russ, J.S. ; Birnbaum, D. ; Edelstein, R.M. ; et al.
Phys.Rev.D 15 (1977) 3139-3154, 1977.
Inspire Record 124704 DOI 10.17182/hepdata.24650

In a single-arm spectrometer experiment, high-precision measurements of dσdt for π−p, K−p, and p¯p elastic scattering have been made at 8 and 16 GeV/c. The π−p data show rich structure at 8 GeV/c, indicative of strong non-Pomeron contributions, while the 16-GeV/c data are much smoother. For −t≳1 (GeV/c)2 there is a strong s dependence while there is very little for −t<1 (GeV/c)2. For p¯p scattering the forward region is smoothly diffractive for −t<0.4 (GeV/c)2 and shows antishrinkage. The exponential slope parameter b is measured to be 12.36 ± 0.04 (GeV/c)−2 at 8 GeV/c and 11.40 ± 0.04 (GeV/c)−2 at 16 GeV/c. The structure near −t=0.6 (GeV/c)2 seen at lower energies is still obvious at 16 GeV/c. The K−p data show some structure at 8 GeV/c, but can be represented adequately by a quadratic exponential form. At 16 GeV/c the K−p angular distribution shows antishrinkage and lies above the 8-GeV/c cross section for 0.11<−t<0.8 (GeV/c)2.

Experimental Results on Elastic Scattering of Protons on the Light Nuclei H-2, H-3, He-3 and He-4 at 600-MeV

Fain, J. ; Gardes, J. ; Lefort, A. ; et al.
Nucl.Phys.A 262 (1976) 413-432, 1976.
Inspire Record 114032 DOI 10.17182/hepdata.37107

Differential cross sections for the elastic scattering of protons on 2 H, 3 H, 3 He and 4 He have been measured at 600 MeV. Proton-deuterium elastic scattering is investigated in a four-momentum transfer square t -range corresponding to Coulomb-nuclear interference in order to determine the nucleon-nucleon amplitudes at 600 MeV. For the other nuclei, we investigate the t -range corresponding to the first and second maximum, in order to determine the mechanism of the nuclear process. A few physical comments on the results are made.

A High Statistics Study of Omega0 Production

Phys.Rev.Lett. 36 (1976) 8, 1976.
Inspire Record 2932 DOI 10.17182/hepdata.37234

We report results from a study of π−p→ω0n at 6.0 GeV/c based on 28 000 events from a charged and neutral spectrometer. Background under the ω0 is only 7%, a large improvement over deuterium-bubble-chamber work. Density matrix elements, projected cross sections, and effective trajectories for natural and unnatural exchanges are presented.

Differential Cross-Section for pi- p --> eta0 n at 6.0-GeV/c

The Carleton-Michigan State-Ohio State-Toronto collaboration Shaevitz, M.H. ; Reay, N.W. ; Reibel, K. ; et al.
Phys.Rev.Lett. 36 (1976) 5, 1976.
Inspire Record 2931 DOI 10.17182/hepdata.21104

We have measured the differential cross section for π−p→η0n at 6.0 GeV/c from 6730 very clean events in which the decay η→π+π−π0 was detected. The high statistics reveals a sizable forward turnover, implying a dominance of the helicity-flip amplitude. A precisely determined A2 trajectory, linear for |t|<1.0 (GeV/c)2, is found from combining our data with those at energies up to 101 GeV.

A missing mass spectrometer search was made for several two-body, double charge exchange reactions, including backward K −p and p̄p elastic scattering at 8 and 16 GeV/ c and small momentum transfer. No examples of any of these processes were observed.

Anti-p-p elastic scattering at 8 and 16 gev/c

Phys.Rev.Lett. 23 (1969) 663-666, 1969.
Inspire Record 56380 DOI 10.17182/hepdata.3393

Angular distributions are presented for p¯−p elastic scattering at 8 and 16 GeV/c for |t|<1.3 (GeV/c)2. At both energies there is structure in the differential cross sections in the region 0.5<~|t|<~1.0 (GeV/c)2, similar to that observed at lower energies. The diffraction peak continues to expand with increasing incident momentum.
