Abstract:

We report a measurement of the differential cross section for W boson production as a function of its transverse momentum in proton-antiproton collisions at √s = 1.8 TeV. The data were collected by the DØ experiment at the Fermilab Tevatron Collider during 1994-1995 and correspond to an integrated luminosity of 85 pb-1. The results are in good agreement with quantum chromodynamics over the entire range of transverse momentum. © 2001 Elsevier Science B.V.

Abstract:

An overview is given of a search for new physics beyond the standard model, assuming nothing about the expected characteristics of the new processes other than they will produce an excess of events at high transverse momentum (PT). A quasi-model-independent strategy (Sleuth) is applied to many exclusive final states in a data sample corresponding to 100 pb1 of pp collisions. The resulting data is analyzed in detail.

Abstract:

The inclusive jet cross section in p̄p collisions at √s = 630 GeV was measured. Many uncertainties in the results were observed. Despite a 10% to 15% difference in the absolute magnitude, the dependence of the ratio on jet transverse momentum was very similar for data and theory.

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.

Ratios of multijet cross sections in pp̄ collisions at √s= 1.8 TeV

Physical Review Letters 86:10 (2001) 1955-1960

Authors:

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.
