Low energy analyzing powers in pion proton elastic scattering.

Meier, R. ; Croni, M. ; Bilger, R. ; et al.
Phys.Lett.B 588 (2004) 155-162, 2004.
Inspire Record 645151 DOI 10.17182/hepdata.26962

Analyzing powers of pion-proton elastic scattering have been measured at PSI with the Low Energy Pion Spectrometer LEPS as well as a novel polarized scintillator target. Angular distributions between 40 and 120 deg (c.m.) were taken at 45.2, 51.2, 57.2, 68.5, 77.2, and 87.2 MeV incoming pion kinetic energy for pi+ p scattering, and at 67.3 and 87.2 MeV for pi- p scattering. These new measurements constitute a substantial extension of the polarization data base at low energies. Predictions from phase shift analyses are compared with the experimental results, and deviations are observed at low energies.

MEASUREMENT OF THE SPIN DEPENDENT PARAMETERS D, R, A, AND P FOR SMALL ANGLE P P ELASTIC SCATTERING BETWEEN 300-MeV AND 600-MeV

Phys.Rev.D 21 (1980) 580-598, 1980.
Inspire Record 157432 DOI 10.17182/hepdata.24184

The Wolfenstein parameters D, R, and A and the polarization parameter P have been measured for p−p elastic scattering at 312, 392, 493, and 575 MeV kinetic energy. The center-of-mass angular range observed was from 3° to 33°. The experiment was performed at SIN, using a polarized proton beam. These data significantly improve the determination of I=1 phase shifts.

MEASUREMENT OF TWO AND THREE SPIN PARAMETERS AT 6-GEV/C USING A TRANSVERSELY POLARIZED BEAM AND TARGET

Beretvas, A. ; Miller, D. ; Auer, I.P. ; et al.
Phys.Rev.D 20 (1979) 21-32, 1979.
Inspire Record 146770 DOI 10.17182/hepdata.24227

Toward the goal of experimentally determining pp elastic scattering amplitudes at 6 GeV/c, we have measured a linear combination of triple-spin correlation parameters and also a linear combination of spintransfer parameters over the |t| range between 0.2 and 1.0 (GeV/c)2. A horizontally polarized beam (S direction) was obtained by precessing the spin of the polarized beam from the Argonne Zero Gradient Synchrotron using a superconducting solenoid. The target protons were polarized vertically (N direction) and the polarization of the recoil protons was measured with a carbon polarimeter. The results are consistent with the amplitude corresponding to π exchange being almost real and positive.

Asymmetry measurements for elastic scattering of k+ mesons by polarized protons

Ehrlich, R.D. ; Etkin, A. ; Glodis, P. ; et al.
Phys.Rev.Lett. 26 (1971) 925-928, 1971.
Inspire Record 69016 DOI 10.17182/hepdata.21466

We report measured values of the asymmetry in the elastic scattering of K+ mesons from polarized protons. The data were obtained at fourteen incident K+ momenta from 1.33 to 2.58 GeVc; the approximate angular range covered was −0.85<cosθKc.m.<0.9. We compare our results with other available measurements and note several significant differences.

The polarization parameter Pn000, the two-spin parameters Dn0n0, Kn00n, Ds0s0, Ds0k0, and the three-spin parameters Ms0sn and Ms0kn have been measured for pp elastic scattering between 34° and 118° center-of-mass scattering angle at six different incident kinetic energies 447, 473, 497, 517, 539, and 560 MeV. The experiment was performed at SIN using a polarized proton beam, a polarized butanol target, and a polarimeter for the measurement of the polarization of the scattered proton.
