Measurements of polarization in pi- p elastic scattering at large angles

Hill, D. ; Koehler, P.F.M. ; Novey, T.B. ; et al.
Phys.Rev.Lett. 27 (1971) 1241-1243, 1971.
Inspire Record 68894 DOI 10.17182/hepdata.229

We have made measurements of polarization in π−p elastic scattering, with emphasis over the backward region, at 1.60 to 2.28 GeVc. The results indicate the absence of u-channel dominance in the backward region, as was observed in the case of π+p scattering. Comparisons have been made with predictions of various phase-shift analyses which show that the agreement is generally very poor in the backward region.

Compton scattering of 3.5 gev polarized photons on protons

Buschhorn, G. ; Criegee, L. ; Franke, G. ; et al.
Phys.Lett.B 37 (1971) 211-212, 1971.
Inspire Record 69081 DOI 10.17182/hepdata.28375

Elastic scattering of linearly polarized photons on protons has been measured between 3.2 and 3.7 GeV for four-momentum transfers ranging from −0.1 to −0.7 (GeV/ c ) 2 . The observed cross section asymmetry in this range is consistent with zero within ±0.05.

Inspire Record 69281 DOI 10.17182/hepdata.28513

The polarization parameter for K + p elastic scattering has been measured at 1.60, 1.80, 2.11 and 3.31 GeV/ c incident momenta over the entire angular range with an emphasis on the backward region. The results in the extreme backward region appear to be small and consistent with zero.

Small momentum transfer pi+ production with linearly polarized photons

Burfeindt, H. ; Buschhorn, G. ; Geweniger, C. ; et al.
Phys.Lett.B 33 (1970) 509-510, 1970.
Inspire Record 69381 DOI 10.17182/hepdata.28537

Previous measurements of the cross section asymmetry for single π + production on protons with linearly polarized photons of 3.4 GeV have been extended to momentum transfers within the forward peak, i.e. − = 0.0026, 0.006 and 0.01 (GeV/ c ) 2 . The results are in good agreement with pion exchange models.

ASYMMETRY IN pi+ PHOTOPRODUCTION FROM A POLARIZED TARGET AT 5-GeV AND 16-GeV

Morehouse, Charles C. ; Borghini, M. ; Chamberlain, Owen ; et al.
Phys.Rev.Lett. 25 (1970) 835, 1970.
Inspire Record 60947 DOI 10.17182/hepdata.3373

We have measured the asymmetry of the cross section for γp→π+n from a polarized target at 5 and 16 GeV. The range of four-momentum transfer was 0.02<~−t<~1.0 GeV2. The π+ mesons were produced in a polarized butanol target and detected with the Stanford Linear Accelerator Center 20−GeVc spectrometer. A sizable asymmetry was found at both 5 and 16 GeV, a typical value being -0.6 near −t=0.3 GeV2. A small amount of data on the asymmetry of other photoproduction processes was also obtained.
