Large $p^-$transverse**2 Spin Effects in $p p \to p p$

Peaslee, D.C. ; O'Fallon, J.R. ; Simonius, M. ; et al.
Phys.Rev.Lett. 51 (1983) 2359, 1983.
Inspire Record 192857 DOI 10.17182/hepdata.20491

The analyzing power A in 28-GeV/c proton-proton elastic scattering was measured with a polarized proton target and a high-intensity unpolarized proton beam at the Brook-haven National Laboratory alternating-gradient synchrotron. The P⊥2 range of 2.85 to 5.95 (GeV/c)2 was covered with good precision. A small dip of about -3.5% was found near P⊥2=3.5 (GeV/c)2 where a 24-GeV/c CERN experiment had reported a deep dip of about -16% with large errors. In the previously unexplored large-P⊥2 region near 6 (GeV/c)2 these new large-error points suggest that A may be rising.

Spin Rotation Measurements in $\pi^- p \to K^0 \Lambda$

Bell, Kenneth Watson ; Blissett, J.A. ; Broome, T.A. ; et al.
Nucl.Phys.B 222 (1983) 389-410, 1983.
Inspire Record 190232 DOI 10.17182/hepdata.33946

The first measurements of spin-rotation in meson-baryon scattering in the resonance region are presented. These measurements, for the reaction π − p → K 0 Λ , confirm the main predictions of a previous partial-wave analysis. Comments are made on resonant couplings in the reaction π − p → K 0 Λ .

EXPERIMENTAL STUDIES OF THE SIGMA, T, P POLARIZATION PARAMETERS AND THE GAMMA P ---> P PI0 REACTION MULTIPOLE ANALYSIS IN THE FIRST RESONANCE REGION

A description is given of the experimental techniques and investigation results of the parameters Σ , T , P for the γ p→p π 0 reaction using linear polarized photons and a polarized proton target. The measurements have been made in the photon energy range 280–450 MeV at pion c.m. angles between 60° and 135°. The new experimental data are used in an energy-independent channel multipole analysis without the Watson theorem.

ANALYZING POWER FOR THE P (polarized) P ---> D PI+ REACTION AT 0.8-GEV AND EFFECTS OF DIBARYON ADMIXTURES

Seth, K.k. ; Saha, A. ; Kielczewska, D. ; et al.
Phys.Lett.B 126 (1983) 164-168, 1983.
Inspire Record 194165 DOI 10.17182/hepdata.30706

A precision measurement of the angular distribution of the analyzing power of the reaction p + p → d + π + has been made at 0.8 GeV. It is shown that none of the existing theoretical calculations, including those which introduce resonant dibaryon amplitudes, reproduce even the qualitative features of the data. It is concluded that our data do not require dibaryon admixtures of the kind proposed for the interpretation of recent data on vector analyzing power, i T 11 (θ), of π− d elastic scattering at the same center of mass energy.

SPIN DEPENDENT PARAMETERS P (NOOO), D (NONO), K (NOON), D (SOSO), D (SOKO), M (SOSN), AND M (SOKN) IN P P ELASTIC SCATTERING AT 579-MEV

Phys.Rev.D 27 (1983) 2600-2616, 1983.
Inspire Record 195612 DOI 10.17182/hepdata.23816

The polarization parameter Pn000, the two-spin parameters Dn0n0, Kn00n, Ds0s0, and Ds0k0, and the three-spin parameters Ms0sn and Ms0kn have been measured for pp elastic scattering at 579 MeV between 34° and 118° center-of-mass scattering angle. 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. These data form the basis for a complete experimental determination of the scattering amplitudes.
