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.

Measurements of Spin Parameters in $p p$ Elastic Scattering at 6-{GeV}/$c$

We measured the differential cross section for proton-proton elastic scattering at 6 GeV/c, with both initial spins oriented normal to the scattering plane. The analyzing power A shows significant structure with a large broad peak reaching about 24% near P⊥2=1.6 (GeV/c)2. The spin-spin correlation parameter Ann exhibits more dramatic structure, with a small but very sharp peak rising rapidly to about 13% at 90°c.m.. This sharp peak may be caused by particle-identity effects.

Cross sections or upper limits are reported for 12 meson-baryon and two baryon-baryon reactions for an incident momentum of 9.9 GeV/c, near 90° c.m.: π±p→pπ±,pp±,π+°±,K+Σ±, (Λ0/Σ0)K0; K±p→pK±; p±p→pp. By studying the flavor dependence of the different reactions, we have been able to isolate the quark-interchange mechanism as dominant over gluon exchange and quark-antiquark annihilation.

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.

DECAY DISTRIBUTION OF HIGH TRANSVERSE MOMENTUM RHO MESONS

Heppelmann, S. ; Blazey, G.C. ; Baller, B. ; et al.
Phys.Rev.Lett. 55 (1985) 1824-1827, 1985.
Inspire Record 221964 DOI 10.17182/hepdata.20301

The exclusive process π−p→ρ−p has been measured at 90° c.m. with an incident pion momentum of 9.9 GeV/c. We present data on the angular dependence of the decay ρ−→π−π0. We observe a strong azimuthal dependence in the decay in the c.m. helicity frame of the ρ. Such an azimuthal dependence is not compatible with SU(6) valence-quark perturbation calculations.
