Measurement and Phase Shift Analysis of the p Parameter in pi+ p Scattering at 236-MeV

Amsler, Claude ; Rudolf, F. ; Weymuth, P. ; et al.
Phys.Lett.B 57 (1975) 289-292, 1975.
Inspire Record 103210 DOI 10.17182/hepdata.27848

The P parameter for π + p scattering at 236.3 MeV has been measured between 50° and 146° c.m. with very low background using a butanol polarized proton target. The resulting D phases are in fair agreement with dispersion relation values.

The recoil proton polarization in the reaction gamma p ---> pi0 p in the third resonance region

Prentice, M.N. ; Railton, R. ; Rutherglen, J.G. ; et al.
Nucl.Phys.B 41 (1972) 353-364, 1972.
Inspire Record 75162 DOI 10.17182/hepdata.32916

Measurements have been made of the polarization of the recoil proton in the process γ p → π o p for photon energies of 850 - 1250 MeV and centre-of-mass angles of 80° - 125°. The results, which are to a typical accuracy of ±0.09, show a marked disagreement with previous phenomenological analyses above 1000 MeV.

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 .
