Jet Algorithms at DØ

Abstract

The DØ experiment at the Fermilab Tevatron proton-antiproton collider $(\sqrt {s} = 1.8{\text{ TeV}})$ accumulated a large sample of high energy jet production data during Run 1 (1992–1996). Since March 2001, DØ has engaged in continuous data collection with an upgraded detector equipped for the higher energy $(\sqrt {s} = 1.96{\text{ TeV}})$ and luminosity conditions of the Run 2 Tevatron. We summarize here pivotal measurements of Run 1 and consider their comparison to theoretical predictions and to other experiments. These factors elucidate DØ’s jet clustering algorithm strategy for Run 2 jet measurements. Preliminary measurements of jets from the Run 2 DØ experiment are also presented.
