Simultaneous Measurement of the Spin Parameters p and c(n n) in p p Elastic Scattering at 2, 3, 4, and 6-GeV/c

Miller, D. ; Wilson, C. ; Giese, R. ; et al.

Phys.Rev.D 16 (1977) 2016-2026, 1977.

Inspire Record 126510 DOI 10.17182/hepdata.24496

Using the polarized-beam facility at Argonne National Laboratory and a polarized proton target, simultaneous measurements of the spin parameter P and the spin correlation term CNN were made. Data were obtained and analyzed at beam momenta of 2, 3, 4, and 6 GeV/c in the momentum-transfer-squared interval 0.1≤|t|≤2.8 (GeV/c)2. A preliminary phase-shift analysis of the 2- and 3-GeV/c data is discussed and a comparison with predictions of a particular Regge-pole model at all four energies is made.

Measurement of the Spin Spin Correlation Parameter C(SS) in p p Elastic Scattering at 6-GeV/c

Auer, I.P. ; Hill, D. ; Miller, R.C. ; et al.

Phys.Rev.Lett. 37 (1976) 1727, 1976.

Inspire Record 4268 DOI 10.17182/hepdata.21043

We have made the first measurement of the spin-spin correlation parameter CSS in pp elastic scattering at 6 GeV/c over the |t| range from 0.05 to 1.5 (GeV/c)2. The measured CSS data points are all negative, and their absolute values increase with |t|. The results are compared with some existing attempts to describe the pp scattering process.

Polarization Measurements around the Secondary Dip in pip Elastic Scattering

Auer, P. ; Giese, R. ; Hill, D. ; et al.

Phys.Rev.Lett. 37 (1976) 83-84, 1976.

Inspire Record 945158 DOI 10.17182/hepdata.21039

Polarization in π−p elastic scattering, with emphasis in the region around the secondary dip and also θc.m.=90°, has been measured at 2.93 and 3.25 GeV/c. We observe an interesting sign change in this angular region.

Measurement of the Polarization in Backward Angle pi- p Elastic Scattering at 2.93-GeV/c and 3.25-GeV/c

Auer, P. ; Bridges, D. ; Droege, T. ; et al.

Nucl.Phys.B 113 (1976) 279-284, 1976.

Inspire Record 3320 DOI 10.17182/hepdata.35605

Polarization in π − p elastic scattering, with emphasis over the backward region, has been measured at 2.93 and 3.25 GeV/ c . We observe large changes in polarization compared with existing data above and below these energies. Our data may be useful in determining the properties of resonances and in understanding baryon exchanges.

Energy Dependence of the Parameter C(NN) at 2-GeV/c, 3-GeV/c, 4-GeV/c and 6-GeV/c

Miller, D. ; Wilson, C. ; Giese, R. ; et al.

Phys.Rev.Lett. 36 (1976) 763, 1976.

Inspire Record 3049 DOI 10.17182/hepdata.21077

We have measured the spin-spin correlation parameter CNN at 2, 3, 4, and 6 GeV/c over the |t| range of 0.1 to 2.0 (GeV/c)2 and have observed a striking energy and |t| dependence in CNN. Polarization data were simultaneously collected and are compared to previous results.

K0(L) p Interactions at 550-MeV/c

Cho, Y. ; Derrick, M. ; Miller, R.J. ; et al.

Phys.Lett.B 60 (1976) 293-296, 1976.

Inspire Record 2899 DOI 10.17182/hepdata.27718

Differential and channel cross sections and hyperon polarizations are presented for the reactions K L o p → K S o p, π + Λ o , and π + Σ o at an average beam momentum of 550 MeV/ c . These data provide constraints on KN and K N amplitudes obtained from charged kaon reactions and reject one of the S = +1, I = 0 and one of the S = -1, I = 1 phase shift solutions.

Phys.Rev.D 12 (1975) 2594, 1975.

Inspire Record 91591 DOI 10.17182/hepdata.24849

As part of a program to determine proton-proton elastic-scattering amplitudes, we have measured the spin-spin correlation parameter CNN at 6 GeV/c. Measurements were made over the |t| range of 0.08 to 1.4 (GeV/c)2 using a polarized beam and a polarized target at the Argonne National Laboratory Zero Gradient Synchrotron.

Sigma+ polarization in pi+ n ---> k0 sigma+ from 1.1 to 2.4 gev/c

Phys.Rev.D 7 (1973) 3546-3548, 1973.

Inspire Record 82052 DOI 10.17182/hepdata.22133

We observe an energy-dependent polarization of the Σ+ produced in the reaction π+n→K0Σ+ at incident beam momenta between 1.1 and 2.4 GeV/c. These data form a significant source of information on the Σ− polarization in the charge-symmetric reaction π−p→K+Σ−.
