Measurement of $\pi^{\pm}$p Backward Elastic Scattering Between 30 and 90 GeV/c

Baker, W.F. ; Eartly, David P. ; Kalbach, R.M. ; et al.
Phys.Rev.Lett. 43 (1979) 1635, 1979.
Inspire Record 141766 DOI 10.17182/hepdata.20758

Measurements of π±p backward elastic scattering have been made for incident pion momenta between 30 and 90 GeV/c and for 0<−u<0.5 (GeV/c)2. The momentum dependence of the cross sections is of a form expected from a simple Regge model, and the u dependence of the cross sections is similar to that observed at lower momenta.

EXCLUSIVE RHO PRODUCTION BY VIRTUAL PHOTONS

Ahrens, L.A. ; Berkelman, Karl ; Cassel, D.G. ; et al.
Phys.Rev.Lett. 42 (1979) 208, 1979.
Inspire Record 129526 DOI 10.17182/hepdata.20809

The cross section for production of ρ0 mesons has been measured in the reaction e+p→e+p+π++π−. The cross section is presented as a function of W, the c.m. energy of the virtual-photon-proton system, and -Q2, the square of the virtual-photon mass. The vector-dominance model is not able to describe the dependence of the cross section on the parameters Q2 and W. The slope parameter B describing the scattering of the proton exhibits a significant variation with Q2.

Observation of Structure in Large Momentum Transfer $\pi^- p$ Elastic Scattering at 200 GeV/c

Baker, W.F. ; Eartly, David P. ; Klinger, J.S. ; et al.
Phys.Rev.Lett. 47 (1981) 1683, 1981.
Inspire Record 167904 DOI 10.17182/hepdata.20628

Results are presented on the measurement of 200-GeV/c π−p elastic scattering at −t from 0.8 to 11 (GeV/c)2. As −t is increased, dσdt falls by ∼6 decades to a prominent dip at 4 (GeV/c)2, followed by a second maximum and than a slow decrease with increasing −t.

Large Momentum Transfer Elastic Scattering of $\pi^{\pm}, K^{\pm}$, and $\rho^{\pm}$ on Protons at 100 GeV/c and 200 GeV/c

Rubinstein, R. ; Baker, W.F. ; Eartly, David P. ; et al.
Phys.Rev.D 30 (1984) 1413, 1984.
Inspire Record 202682 DOI 10.17182/hepdata.23648

Results are presented on π±p, K±p, and p±p elastic scattering measured with an apparatus having acceptance of 0.5<−t<2.5 (GeV/c)2 and 0.9<−t<11 (GeV/c)2 at 100 and 200 GeV/c, respectively. A diffractionlike dip is seen for the first time in the π−p t distribution at −t=4 (GeV/c)2. All meson-proton cross sections are found to be similar in the range 1<−t<2.5 (GeV/c)2, although some small systematic differences are observed. Cross sections for pp and p―p are compared with previous data.

Elastic Scattering of $\pi^{\pm}$ and $K^{\pm}$ on Protons at 100-GeV/c and 200-GeV/c

Kalbach, R.M. ; Krueger, K.W. ; Pifer, A.E. ; et al.
Phys.Rev.D 27 (1983) 2752-2754, 1983.
Inspire Record 195613 DOI 10.17182/hepdata.23833

Data are presented on elastic πp and Kp scattering for values of −t up to 2.5 and 3.5 (GeV/c)2 at incident momenta of 100 and 200 GeV/c, respectively. All of the cross sections are found to be nearly identical, although there is some momentum dependence of the π+p data; a small systematic difference observed between pion and kaon data cannot be explained by geometrical scaling.

Antiproton - Proton and Proton - Proton Elastic Scattering at 100 and 200 GeV/c

Kaplan, D.H. ; Karchin, P. ; Orear, J. ; et al.
Phys.Rev.D 26 (1982) 723, 1982.
Inspire Record 178011 DOI 10.17182/hepdata.23894

Antiproton-proton elastic scattering has been measured at 100 GeV/c for 0.5<−t<2.5 (GeV/c)2 and at 200 GeV/c for 0.9<−t<4 (GeV/c)2. The data show that the −t≃1.4 (GeV/c)2 dip recently observed at 50 GeV/c persists to higher incident momenta. Proton-proton measurements made at the same beam momenta show similar structure.

Pion-Proton Backward Elastic Scattering Between 30 and 90 GeV/c

Phys.Rev.D 27 (1983) 1999, 1983.
Inspire Record 181377 DOI 10.17182/hepdata.23836

Backward elastic scattering of π± on protons has been measured for incident pion momenta between 30 and 90 GeV/c and 0≤−u≤0.5 (GeV/c)2. The u dependence of the cross sections is similar to that observed at lower momenta, and Regge models give acceptable fits to the data.

The production of the ω meson by virtual photons has been measured as a function of Q2 and W. The ratio of ω production to ρ0 production is independent of Q2 in contrast to indications at lower values of W.
