Abstract:

The D0 Collaboration has measured the inclusive jet cross section in barpp collisions at square root of s = 630 GeV. The results for pseudorapidities (eta)<0.5 are combined with our previous results at square root of s = 1800 GeV to form a ratio of cross sections with smaller uncertainties than either individual measurement. Next-to-leading-order QCD predictions show excellent agreement with the measurement at 630 GeV; agreement is also satisfactory for the ratio. Specifically, despite a 10% to 15% difference in the absolute magnitude, the dependence of the ratio on jet transverse momentum is very similar for data and theory.

Abstract:

The lifetime of the lowest-mass charm bryon is measured to provide a window for the nonperturbative sector of heavy quark decay. The data are obtained in a colliding beam environment in the CLEO II.V detector at the Cornell Electron Storage Ring. In this environment, the event topologies and backgrounds are very different from those encountered in high energy fixed-target experiments.

Abstract:

We report on a study of the ratio of inclusive three-jet to inclusive two-jet production cross sections as a function of total transverse energy in pp̄ collisions at a center-of-mass energy √s = 1.8 TeV, using data collected with the DO detector during the 1992-1993 run of the Fermilab Tevatron Collider. The measurements are used to deduce preferred renormalization scales in perturbative script O (αs3) QCD calculations in modeling soft-jet emission. © 2001 The American Physical Society.

Abstract:

A new measurement of the pseudorapidity (η) and transverse-energy (ET) dependence of the inclusive jet production cross section was carried out. The differential cross section d2σ/(dETdη) was considered as a function of jet ET in five intervals of up to |η| = 3. Results were compared with next-to-leading order predictions from QCD.
