Mesure de la section efficace inclusive de production des jets en fonction de leur impulsion transverse dans l'expérience DØ au Fermilab

Abstract : This work describes the measurement of inclusive jets cross section in the DØ experiment. This cross section is computed as a function of jet transverse momentum, in several rapidity intervals. This quantity is sensitive to the proton structure and is crucial for the determination of parton distribution functions (PDF), essentially for the gluon at high proton momentum fraction. The measurement presented here gives the first values obtained for Tevatron Run II for the cross section in several rapidity intervals, for an integrated luminosity of 143 pb-1. The results are in agreement, within the uncertainties, with theoretical Standard Model predictions, showing no evidence for new physics. This work points out the aspects of the detector wich need better understanding to reach Run I precision and to constrain the PDFs.
