Improved isolation of the p-p underlying event based on minimum-bias trigger-associated hadron correlations

Improved isolation of the p-p underlying event based on minimum-bias trigger-associated hadron correlations Proceedings of the XLIII International Symposium on Multiparticle Dynamics creator Trainor, Thomas creator Prindle, Duncan J. editor Chekanov, Sergei editor Sullivan, Zack Some aspects of hadron production in p-p collisions remain unresolved, including the low-hadron-momentum structure of high-parton-energy dijets, separation of triggered dijets from the underlying event (UE), the systematics of multiple parton interactions and possible systematic underestimation of dijet contributions to high-energy nuclear collisions. In this study we apply a minimum-bias trigger-associated (TA) correlation analysis to p-p collisions. We extract a hard component from TA correlations that can be compared with measured jet fragment systematics derived from e+-e− collisions. The kinematic limits on jet fragment production may be determined. The same method may be extended to A-A collisions where the role of minimum-bias jets in spectra and correlations is strongly contested.
