Comparison of Exclusive Reactions at Large $T$

Baller, B.R. ; Blazey, G.C. ; Courant, H. ; et al.
Phys.Rev.Lett. 60 (1988) 1118-1121, 1988.
Inspire Record 264273 DOI 10.17182/hepdata.3063

Cross sections or upper limits are reported for 12 meson-baryon and two baryon-baryon reactions for an incident momentum of 9.9 GeV/c, near 90° c.m.: π±p→pπ±,pp±,π+°±,K+Σ±, (Λ0/Σ0)K0; K±p→pK±; p±p→pp. By studying the flavor dependence of the different reactions, we have been able to isolate the quark-interchange mechanism as dominant over gluon exchange and quark-antiquark annihilation.

Elastic Scattering of 3.5-BeV/c $\pi^-$ Mesons by Protons

Ainutdinov, M.S. ; Zombkovskii, S.M. ; Pletnikov, A.A. ; et al.
Sov.Phys.JETP 18 (1964) 271-272, 1964.
Inspire Record 1387686 DOI 10.17182/hepdata.70200

THE study of elastic scattering at high energies in the region of the diffraction maximum has gained in interest recently in connection with the verifica- tion of the asymptotic expressions obtained by cal- culating the Regge-pole trajectories. We have in- vestigated the elastic scattering of 3. 5- Be VIc 7r- mesons by protons. The measurements were made with the aid of a liquid-hydrogen bubble chamber 25 em in diameter, placed in a 14 kOe magnetic field.

Negative pion-proton elastic scattering at 1.7 GeV/c

Allen, D.D. ; Fisher, G.P. ; Godden, G. ; et al.
Phys.Lett. 21 (1966) 468-470, 1966.
Inspire Record 1385170 DOI 10.17182/hepdata.29931

The differential elastic scattering cross section for 1.7 GeV/c pion- on protons is evaluated by analysis of Brookhaven 20" bubble chamber film. Primary and secondary diffraction peaks are evident. These are discussed in terms of optical model parameters.

Measurements of spin rotation parameter A in pion proton elastic scattering at 1.62-GeV/c.

The ITEP-PNPI collaboration Alekseev, I.G. ; Budkovsky, P.E. ; Kanavets, V.P. ; et al.
Phys.Lett.B 485 (2000) 32-36, 2000.
Inspire Record 526552 DOI 10.17182/hepdata.41744

The ITEP-PNPI collaboration presents the results of the measurements of the spin rotation parameter A in the elastic scattering of positive and negative pions on protons at P_beam = 1.62 GeV/c. The setup included a longitudinally-polarized proton target with superconductive magnet, multiwire spark chambers and a carbon polarimeter with thick filter. Results are compared to the predictions of partial wave analyses. The experiment was performed at the ITEP proton synchrotron, Moscow.

Asymmetry in $\pi^- P$ (Polarized) Elastic Scattering in Momentum Range 1.4-{GeV}/c - 2.1-{GeV}/c

Alekseev, I.G. ; Budkovsky, P.E. ; Kanavets, V.P. ; et al.
Nucl.Phys.B 348 (1991) 257-275, 1991.
Inspire Record 285067 DOI 10.17182/hepdata.33071

Results of systematic measurements of the asymmetry parameter in the elastic scattering of pions on polarized protons at 1.4–2.1 GeV/ c in the backward hemisphere are presented together with a test of the isospin invariance of the data set available on pion-proton scattering in the investigated momentum range. The transversity isodoublet amplitudes at 1.98 and 2.07 GeV/ c are reconstructed. The obtained data, the isospin analysis and amplitude reconstruction results are compared with the current phase-shift analysis predictions.

BACKWARD SCATTERING IN pi- p ---> p pi-, anti-p p ---> pi+ pi-, K- p ---> p K- AND anti-p p ---> p anti-p AT 8-GeV/c AND 12-GeV/c

The CERN-Lisbon-Moscow-Neuchatel-College de France-Paris collaboration Armstrong, T.A. ; Baubillier, M. ; Brient, J.C. ; et al.
Nucl.Phys.B 284 (1987) 643, 1987.
Inspire Record 230626 DOI 10.17182/hepdata.33525

Data on the reactions π − p → p π − , p p → π + π − , K − p → pK and p p → p p at 8 and 12 GeV/ c are presented. Our results agree with line reversal symmetry (between π − p → p π − and p p → π + π − ), Regge pole behaviour for non-exotic reactions ( π − p → p π − , p p → π + π − ), and universal behaviour for exotic reactions ( p p → p p , K − p → pK − ) with d σ /d u | u =0 ∼ s −10 excluding the existence of a “glory” mechanism in p p elastic backward scattering in our energy range.

MEASUREMENT OF LOW-ENERGY ELASTIC PI+- P DIFFERENTIAL CROSS-SECTIONS

Frank, J.S. ; Browman, A.A. ; Gram, P.A.M. ; et al.
Phys.Rev.D 28 (1983) 1569-1585, 1983.
Inspire Record 196833 DOI 10.17182/hepdata.23815

We have measured differential cross sections for both π+p and π−p elastic scattering at incident-pion kinetic energies of 30, 50, 70, and 90 MeV in the center-of-mass angular range between 50° and 150°. The experiment detected pions scattered from a liquid-hydrogen target with multiwire proportional chambers and scintillation-counter range telescopes. The relative accuracy of each angular distribution is better than 5%, while the absolute cross sections have uncertainties of 4% to 25%. Our results for the absolute cross section for π+p scattering at 30 and 90 MeV are inconsistent with previous measurements. Our π−p measurements comprise the first extensive set of precision differential cross sections below 90 MeV.
