CUSP IN PI- P ELASTIC SCATTERING AT THE ETA THRESHOLD

Sarma, H.N.K. ; Binnie, D.M. ; Carr, J. ; et al.
Nucl.Phys.B 161 (1979) 1-13, 1979.
Inspire Record 147683 DOI 10.17182/hepdata.34612

We present results from a high momentum resolution measurement of the π − p elastic differential cross section near the η production threshold. By analysing the cusp discontinuity in the elastic cross section we deduce the non-spin-flip elastic amplitude and compare it with solutions from phase-shift analyses.

Inspire Record 98421 DOI 10.17182/hepdata.32031

Differential cross sections for elastic scattering of negative kaons on protons are presented for 13 incident laboratory momenta between 1094 MeV/c and 1377 MeV/c. The data show the characteristic forward diffraction-like peak and backward dip and are adequately described in shape by certain published partial-wave analyses of the N system.

Large-Angle Pion-Proton Elastic Scattering at High Energies

Orear, J. ; Rubinstein, R. ; Scarl, D.B. ; et al.
Phys.Rev. 152 (1966) 1162-1170, 1966.
Inspire Record 50774 DOI 10.17182/hepdata.407

Differential cross sections for elastic π±−p scattering have been measured at lab momenta of 8 and 12 GeV/c in a momentum-transfer region corresponding to 1.2≤−t≤6 (GeV/c)2. Also, differential cross sections near 180° were measured for 4 and 8 GeV/c pions. At momentum transfers greater than −t=2 (GeV/c)2, the π−p cross sections drop much faster with increasing angle than the corresponding p−p cross sections. Also, in the region −t≃1.3 (GeV/c)2, there is structure in the π−p angular distribution but not in the p−p angular distribution. At −t≃3 (GeV/c)2, the drop in cross section appears to stop and from then on the angular distribution is consistent with isotropy. But in the angular region 170° to 180°, the cross sections have become much larger, and sharp backward peaks are observed. Information is given on the energy and charge dependences and widths of these backward peaks.

Pi-minus p elastic scattering at 2.51, 2.76, and 3.01 gev/c near t approximately equals -3 (gev/c)-squared

Fellinger, M. ; Gutman, E. ; Lamb, R.C. ; et al.
Phys.Rev.Lett. 23 (1969) 600-602, 1969.
Inspire Record 58788 DOI 10.17182/hepdata.21636

Differential cross sections for the elastic scattering of negative pions from hydrogen have been measured over a limited range of squared four-momentum transfer (t) in the vicinity of t≃−3 (GeV/c)2 for incident pion momenta of 2.51, 2.76, and 3.01 GeV/c. These measurements confirm the existence of a minimum in the differential cross section in this region of incident momentum and scattering angle. The minimum occurs at a smaller value of t [t≃−2.6 (GeV/c)2] than has been observed at higher momenta.

Pi- p elastic scattering near 180 degrees between 600 and 1280 mev/c

Crabb, D.G. ; Keller, R. ; O' Fallon, J.R. ; et al.
Phys.Rev.Lett. 27 (1971) 216-219, 1971.
Inspire Record 68952 DOI 10.17182/hepdata.21460

The differential cross sections for π−p elastic scattering over the angular range 155° to 177° in the center of mass have been measured at 33 incident-pion momenta in the range 600 to 1280 MeV/c. Angular distributions are presented. The extrapolated differential cross sections at 180° show considerable structure, in particular a dip near 1150 MeV/c. In general the near-180° cross sections do not agree with existing phase shift solutions above 1000 MeV/c

Backward $K^- p$ Elastic Scattering and 0-degree $\Sigma^- \pi^+$ Production

Phys.Rev.D 21 (1980) 1191-1205, 1980.
Inspire Record 131715 DOI 10.17182/hepdata.24193

In this paper we report measurements of the backward K−p differential cross section at 49 momenta covering the momentum range 476-1084 MeV/c. The statistical precision achieved, typically 2.5%, is an order of magnitude better than previous measurements. The systematic errors for this reaction are about 1%. The differential cross section for the reaction K−p→Σ−π+ where the π+ emerges at 0° has also been measured at 32 momenta with comparable improvement in precision over previous experiments. A partial-wave analysis of the K¯N channels including the new K−p backward elastic data is presented.

Measurement of Differential Cross-Sections in pi+ p Backward Elastic Scattering Between 1.25-GeV/c and 2-GeV/c

Ott, R.J. ; Trischuk, J.M. ; Va'vra, Jaroslav ; et al.
Phys.Rev.D 16 (1977) 2699-2705, 1977.
Inspire Record 126662 DOI 10.17182/hepdata.24495

As part of a program of measurements of the πp system we have measured the backward differential cross section for π+p elastic scattering at 16 momenta from 1.25 to 2.0 GeV/c inclusive. The angular region covered is -0.46 to -0.97 in cosθc.m.. The high resolution in u of 0.03 to 0.04 (GeV/c)2, together with good statistics, enables a detailed examination of the momentum and angular dependence of structure in this channel. The data are compared with distributions from other experiments and with the most recent phaseshift fit.

Small Angle p p Elastic Scattering at Energies Between 285-MeV and 572-MeV

Aebischer, D. ; Favier, B. ; Greeniaus, L.G. ; et al.
Phys.Rev.D 13 (1976) 2478-2498, 1976.
Inspire Record 114031 DOI 10.17182/hepdata.24779

Differential cross sections for elastic p−p scattering have been measured at 285, 348, 398, 414, 455, 497, 530, and 572 MeV kinetic energy. The experiment was performed at the CERN synchrocyclotron, using multiwire proportional chambers placed directly in a proton beam. Scattering was observed for 1.5°≲θ≲10° in the laboratory system. The ratio αp of the real and imaginary parts of the non-spin-flip nuclear forward amplitude was derived from the interference between the Coulomb and nuclear amplitudes. The values obtained are model-dependent, but in this energy range αp is positive and decreases with energy. Qualitatively good agreement with dispersion-relation predictions is observed.
