Jet & Underlying Event Measurements in p-p collisions at RHIC

Abstract

The physics of hadron-hadron collisions is very complex involving both perturbative and non-perturbative QCD. It is therefore imperative to study p-p collisions in as much detail as possible to provide a wide variety of data against which the various theoretical calculations can be tested. Direct jet measurements, for instance, help address fundamental questions of the fragmentation process. These measurements form a critical baseline for comparisons of results from heavy-ion studies, where modifications of the fragmentation functions are expected due to interactions of the high $Q^2$ scattered partons with the hot and dense medium. Finally, it is also important to gain a deeper understanding of how the beam-beam remnants, multi-parton interactions and initial- and final-state radiation combine to produce the particles observed in the underlying event. In this talk we present results on jet production and the underlying event in p-p collisions at 200 GeV collisions as measured by the STAR experiment at RHIC.
