Recent QCD results from D0 at the Tevatron

PDF Version Also Available for Download.

Description

The D0 experiment at the Tevatron proton-antiproton collider accumulated a large sample of high energy jet production data during Run I (1992-1996). Presented here are measurements of the inclusive jet cross section at a center-of-mass energy {radical}s = 1800 GeV, and a ratio of central inclusive jet cross sections at two different center-of-mass energies (1800 and 630 GeV). Also included is a measure of the ratio of multijet production cross sections at the higher {radical}s: All measurements are compared to next-to-leading order QCD predictions with recent parton distribution functions (PDFs). Due to decreased statistical and systematic errors in the measurement, ... continued below

Description

The D0 experiment at the Tevatron proton-antiproton collider accumulated a large sample of high energy jet production data during Run I (1992-1996). Presented here are measurements of the inclusive jet cross section at a center-of-mass energy {radical}s = 1800 GeV, and a ratio of central inclusive jet cross sections at two different center-of-mass energies (1800 and 630 GeV). Also included is a measure of the ratio of multijet production cross sections at the higher {radical}s: All measurements are compared to next-to-leading order QCD predictions with recent parton distribution functions (PDFs). Due to decreased statistical and systematic errors in the measurement, comparison with the theory shows that the prediction may benefit from an increased order in the calculation and from inclusion of proton-antiproton jet data in new global PDF fits.
