Abstract

We describe a comprehensive survey of two-particle correlations from p-p collisions at $\sqrt{s} = 200$ GeV. Correlations on transverse rapidity $y_t$ are separated into a soft component (string fragments) and a hard component (parton fragments). Fragment correlations on transverse rapidity $y_t$ are compared to fragmentation functions on logarithmic momentum variable $\xi$ . Cuts on transverse rapidity isolate angular correlations on $(\eta,\phi)$ for the two components. Hard-component angular correlations are compared to results from conventional leading-particle jet analysis. Angular correlations for low- $p_t$ fragments, corresponding to low- $Q^2$ parton scattering, reveal a large asymmetry about the jet thrust axis.
