Positron-Proton Elastic Scattering at 800 and 1200 MeV

Anderson, R.L. ; Borgia, B. ; Cassiday, G.L. ; et al.
Phys.Rev. 166 (1968) 1336-1342, 1968.
Inspire Record 944943 DOI 10.17182/hepdata.26527

The cross section for the elastic scattering of positrons from protons has been compared with the corresponding electron cross section using secondary beams derived from the photon beam of the Cornell 2-GeV synchrotron. The paths of the scattered leptons (positrons or electrons) and recoil protons were recorded in spark chambers and were used to determine the incident lepton energy of each event. Elastic scatterings were identified by requiring coplanarity and a fit to the scattering kinematics. The detection system was sensitive to scattering angles between 25° and 75°. The ratio of the positron cross section to the corresponding electron cross section was 0.992±0.017 at 800 MeV and 0.987±0.019 at 1200 MeV. No significant variation of the ratio with angle of scattering was found.

Anti-p-p backward elastic scattering from 0.7 to 2.16 gev/c

Yoh, J.K. ; Barish, B.C. ; Nicholson, H. ; et al.
Phys.Rev.Lett. 23 (1969) 506-510, 1969.
Inspire Record 56393 DOI 10.17182/hepdata.3399

Elastic scattering of p¯ on p has been studied for cosθc.m. between -0.88 and -1.0 and Plab(p¯) between 0.70 and 2.16 GeV/c. The momentum dependence of the cross section shows a sharp dip at 0.9 GeV/c and a broad peaking around 1.4 GeV/c. The possibility of the peak resulting from direct formation of boson resonances has been studied. Alternatively, a diffraction model agrees qualitatively with our data and other elastic data at different angles.

Study of neutral final states produced in pi-minus p collisions at momenta of 1.71-2.46 gev/c

Carroll, A.S. ; Corbett, I.F. ; Damerell, C.J.S. ; et al.
Phys.Rev. 177 (1969) 2047-2066, 1969.
Inspire Record 55660 DOI 10.17182/hepdata.5504

We have studied neutral final states produced in π−p collisions at momenta of 1.71, 1.89, 2.07, 2.27, and 2.46 GeVc, by observing the γ rays emitted. In particular, measurements are presented of (i) π−p→π0n, for which the Regge-pole fit at momenta ≥5.9 GeVc also agrees rather well here; (ii) π−p→η0n, for which the Regge model which fits at higher energies does not agree here; (iii) π−p→π0γn, in which there is some evidence for a diffraction dissociation process as well as ω0-meson production; (iv) π−p→π0π0n, which is dominated by production of N*0(1236)π0 and by peripheral production of pion pairs. In (iv), the former process is found to fit with the same Reggeized ρ-meson exchange model as charge-exchange scattering, while the latter gives indication of the s-wave ππ interaction. An account is given of new techniques, particularly in the data analysis, which were developed in the course of this work.

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 .

We have studied the process p¯p into π+X− using wire spark chambers. The data cover the angular range of cosθp¯π+* between 0.96 and 1.0 at several incident momenta between 1 and 2 GeVc. The reaction p¯p→π+ρ− was observed with (dσdΩ)* of the order of 100 μb/sr at several momenta.
