STRUCTURE OBSERVED IN THE SPIN SPIN CORRELATION PARAMETER C(LL) = (L, L, 0, 0) IN P P ELASTIC SCATTERING AROUND THETA (C.M.) = 90-DEGREES IN THE REGION P(LAB) = 2.5-GEV/C - 5.0-GEV/C

The spin-spin correlation parameter CLL=(L, L; 0, 0) has been measured for p−p elastic scattering around θc.m.=90° up to plab=5 GeV/c. An interesting energy dependence is observed in CLL and the results are interpreted by comparison with other available data.

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.

Measurements of the Total Cross-Section Difference and the Parameter C(LL) in p p Scattering with Longitudinally Polarized Beam and Target

We have measured the difference between the pp total cross-sections for parallel and anti-parallel longitudinal spin states at beam momenta of 3 and 6 GeV/ c . These results, combined with our previous measurements, at lower momenta, are useful in clarifying a striking structure appearing at around 1.5 GeV/ c . We have also measured for the first time, the spin-spin correlation parameter C LL ( t ) in pp elastic scattering at 6 GeV/ c . We observe evidence for an exchange with A 1 -like quantum-numbers.
