Measurement of the Difference in $P N$ Total Cross-sections in Pure Longitudinal Spin States

Auer, I.P. ; Ditzler, W.R. ; Hill, D. ; et al.
Phys.Rev.Lett. 46 (1981) 1177-1180, 1981.
Inspire Record 170180 DOI 10.17182/hepdata.20657

The total-cross-section difference in pure longitudinal spin states for p−d interactions has been measured at momenta from 1.1 to 6 GeV/c. Spin-dependent Glauber-type corrections and other corrections have been made to obtain ΔσL(pn) and ΔσL(I=0). These measurements are of fundamental interest and will also help in determining the existence and nature of dibaryon resonances.

Phys.Rev.Lett. 41 (1978) 1436, 1978.
Inspire Record 131077 DOI 10.17182/hepdata.20865

We have measured the spin-spin correlation parameter CLL=(L, L;0, 0) in p−p elastic scattering around θc.m.=90° from plab=1.0 to 3.0 GeV/c. We observe a rapid energy dependence in CLL and describe our interpretation of the results.

Observation of Structures in the p p Total Cross-Section Difference of Pure Helicity States in the Mass Range of 2100-MeV to 2500-MeV

Auer, I.P. ; Colton, E. ; Halpern, H. ; et al.
Phys.Rev.Lett. 41 (1978) 354-356, 1978.
Inspire Record 135492 DOI 10.17182/hepdata.20831

We have measured the difference between the pp total cross sections for parallel and antiparallel longitudinal spin states at beam momenta of 1.0, 1.1, 1.30, 1.58, 1.71, 2.1, and 2.25 GeV/c in a transmission counter experiment. These results reveal new structure in the plab range of 1.0 to 2.5 GeV/c.

Measurements of the Spin Rotation Parameter R in p p and pi+ p Elastic Scattering at 45-GeV/c

The SERPUKHOV-SACLAY-DUBNA-MOSCOW collaboration Pierrard, J. ; Bruneton, C. ; Bystricky, J. ; et al.
Phys.Lett.B 61 (1976) 107-109, 1976.
Inspire Record 113035 DOI 10.17182/hepdata.27706

The spin rotation sf R in pp and π + p elastic scattering at 45 GeV/c has been measured at the Seppukhov accelarator, for z . sfnc ; t |; ranging from 0.2 to 0.5 (GeV/) 2 . The results are presented, together with previous R measurements at lower energies. The equality of the values for R in proton-proton and pion-proton scattering, within the experimental errors, is a test of factorization of the residues in the pomeron exchange.

Measurements of Polarization and Spin Rotation in Proton Proton Elastic Scattering at 3.83-GeV/c

Deregel, J. ; Bruneton, C. ; Bystricky, J. ; et al.
Nucl.Phys.B 103 (1976) 269-278, 1976.
Inspire Record 113032 DOI 10.17182/hepdata.35989

The polarization P in proton-proton elastic scattering has been measured at 3.83 GeV/ c for 0.35 ⩽ | t | ⩽ 3.0 (GeV/ c ) 2 , i.e. 29° ⩽ θ c.m. ⩽ 93°. The polarization shows a minimum at − ⋍ 1.0 ( GeV /c) 2 followed by a maximum at −⋍1.5 ( GeV /c) 2 . At the same energy the spin rotation parameter R has been measured in the interval 0.18 ⩽ | t | ⩽ 0.57 (GeV/ c ) 2 . Comparison with the results at 6.0 and 15.75 GeV/ c shows a similar t -dependence and the same average value at all three energies.

On Measuring Spin Rotation Parameter r in pi- p and K- p Elastic Scattering at 40-GeV/c

The Serpukhov-Saclay-Dubna-Moscow collaboration Pierrard, J. ; Bruneton, C. ; Bystricky, J. ; et al.
Phys.Lett.B 57 (1975) 393-397, 1975.
Inspire Record 99593 DOI 10.17182/hepdata.27839

The spin rotation parameter R has been measured for elastic π − p scattering at 40 GeV/ c , at four momentum transfers t ranging from −0.19 to −0.52 (GeV/ c ) 2 . The average value within this interval is R π − p = -0.200± 0.023. The resulting constraints on the πN scattering amplitudes are discussed. The experiments also yields an average value for K − p scattering, R K − p scattering, R K − p = -0.16±0.16.

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.

Measurement of Asymmetries in Polarized gamma + n --> pi + n, with E(gamma) from 600-MeV to 900-MeV

Phys.Rev.D 10 (1974) 2778, 1974.
Inspire Record 90220 DOI 10.17182/hepdata.24943

We report on the measurement of asymmetries in the single-pion photoproduction reactions γp→nπ+, γp→pπ0, and γn→pπ−, induced by linearly polarized photons of energies from 610 to 940 MeV. The experiment was carried out using the back-scattered laser beam and the 82-in. dubble chamber at SLAC. We compare the new data with predictions from a partial-wave analysis.

Measurement of the spin rotation parameter r in proton proton elastic scattering at 6 and 16 gev/c

Deregel, J. ; Bystricky, J. ; Cozzika, G. ; et al.
Phys.Lett.B 43 (1973) 338-340, 1973.
Inspire Record 84912 DOI 10.17182/hepdata.28132

The spin rotation parameter R in elastic proton-proton scattering has been determined at incident momenta 6 and 16 GeV/ c in the interval from t = −0.18 (GeV/ c ) 2 to −0.54 (GeV/ c ) 2 . R pp at 16 GeV/ c is close to the val obtained for R in π − p elastic scattering at the same incident momentum. Equality of R pp ( s , t ) and R π p ( s , t ) is expected if Pomeron exchange dominates and if factorization holds. The t -dependence of R at 16 GeV/ c is consistent with weak helicity flip.
