ANALYZING POWER IN LARGE ANGLE PROTON NEUTRON ELASTIC SCATTERING

Makdisi, Y. ; Marshak, M.L. ; Mossberg, B. ; et al.
Phys.Rev.Lett. 45 (1980) 1529-1533, 1980.
Inspire Record 159455 DOI 10.17182/hepdata.20701

The large-angle analyzing power A in proton-neutron elastic scattering at 2, 3, and 6 GeV/c with use of the polarized proton beam at the Argonne zero-gradient synchrotron and a liquid deuterium target have been measured. The measurements, the first at high energy, show that A is large (20-40%) and negative over much of the angular range and shows no decrease with incident energy, unlike the earlier data at smaller angles.

Polarization in p p Elastic Scattering at Small |t|

Klem, R.D. ; Courant, H.W. ; Lee, J. ; et al.
Phys.Rev.D 15 (1977) 602-603, 1977.
Inspire Record 124114 DOI 10.17182/hepdata.24547

We have measured the polarization parameter for proton-proton elastic scattering at p0 = 6 GeV/c for |t|<0.5 (GeV/c)2 using the polarized proton beam at the Argonne Zero Gradient Synchrotron. These data, together with all previous measurements in this t region, are well fitted by the empirical relation P = (0.481±0.010)(−t)12exp(2.291±0.085)t.

A Measurement of the Energy Dependence of Elastic $\pi p$ and $p p$ Scattering at Large Angles

Jenkins, K.A. ; Price, L.E. ; Klem, R. ; et al.
Phys.Rev.Lett. 40 (1978) 425, 1978.
Inspire Record 6233 DOI 10.17182/hepdata.3359

We have measured π±p and pp elastic differential cross sections in the range |cosθc.m.|<0.35 for incident momenta from 2 to 9.7 GeV/c for π−p and pp and from 2 to 6.3 GeV/c for π+p. We find that the fixed-c.m.-angle πp differential cross sections cannot be described as simple functions of s. The data are compared to the energy and angular dependence predicted by the constituent model of Gunion, Brodsky, and Blankenbecler.

Hard exclusive hadron nucleon scattering and color transparency

Heppelmann, S. ; Wu, J.Y. ; Appel, R. ; et al.
Nucl.Phys.A 527 (1991) 581C-583C, 1991.
Inspire Record 327578 DOI 10.17182/hepdata.36761

We present preliminary results on the measurement of a variety of exclusive hadron interactions at center of mass scattering angles of 90°. Data are also presented which show the relative transparency of nuclei to πp and pp elastic scattering in this kinematic range.

DEPOLARIZATION PARAMETER IN P P INCLUSIVE SCATTERING AT 6-GEV/C

Courant, H. ; Kagan, H. ; Makdisi, Y. ; et al.
Phys.Rev.Lett. 44 (1980) 1373-1376, 1980.
Inspire Record 158285 DOI 10.17182/hepdata.20737

The depolarization parameter for pp inclusive scattering at an incident momentum of 6 GeV/c was measured. The D parameter for inclusive scattering indicates the dominance of natural-parity exchange at small t, except in the case of N*(1232) production, where π exchange is more important. D for elastic scattering has also been measured. This parameter shows a small decrease from unity with increasing momentum transfer.
