Abstract

Comparisons of particle production from high-energy ion collisions with next-to-leading order perturbative QCD calculations show good agreement down to moderate transverse momentum values. Distributions of azimuthal angle differences between coincident hadrons in these collisions support a partonic origin to the particle production again down to moderate transverse momentum values. The rapidity dependence of inclusive and coincident particle production can therefore be used to probe parton distribution functions down to small momentum fractions where theory anticipates that parton saturation could be present. This paper describes how such experiments could be completed. © Springer-Verlag 2005.

Abstract

The considerable polarization of hyperons produced at high x(F) has been known for a long time and has been interpreted with various theoretical models in terms of the constituents' spin. Recently, the analyzing power in inclusive Lambda(0) hyperon production has also been measured using the 200 GeV/c Fermilab polarized proton beam. The covered kinematic range is 0.2 less than or equal to x(F) less than or equal to 1.0 and 0.1 less than or equal to p(T) less than or equal to 1.5 GeV/c. The data indicate a negative asymmetry at large x(F) and moderate p(T). These results can further test the current ideas on the underlying mechanisms for hyperon polarization.
