QCD at the Tevatron

چکیده

Recent measurements of selected QCD processes at the Tevatron are reviewed and confronted with theoretical calculations. Results on inclusive jet production at large transverse momentum (pT ) are compared to predictions from next-to-leading order (NLO) perturbative QCD (pQCD). Kinematic distributions of jets with light and heavy flavor produced in association with electroweak bosons are compared to expectations from leading-order (LO) QCD calculations supplemented with parton-shower models. Properties of QCD radiation in hard-scatter events are investigated using azimuthal correlations between two leading jets in multi-jet events, while aspects of softer radiation are examined through properties of energy flow within jets. Finally, characteristics of soft interactions underlying the hard scatter are explored in the context of tuning the parameters of phenomenological models employed in QCD Monte Carlo event generators.

Supersymmetric QCD correction to top-quark production at the Tevatron

We calculate the supersymmetric QCD correction to top-quark production at the Fermilab Tevatron, allowing for arbitrary left-right mixing of the squarks. We find that the correction is significant for several combinations of gluino and squark masses, e.g. +33% for m g̃ = 200 GeV, m t̃ = m q̃ = 75 GeV.

Tevatron - for - LHC Report of the QCD Working Group

The experiments at Run 2 of the Tevatron have each accumulated over 1 fb−1 of high-transverse momentum data. Such a dataset allows for the first precision (i.e. comparisons between theory and experiment at the few percent level) tests of QCD at a hadron collider. While the Large Hadron Collider has been designed as a discovery machine, basic QCD analyses will still need to be performed to under...

Recent Qcd Studies at the Tevatron

Since the beginning of Run II at the Fermilab Tevatron, the QCD physics groups of the CDF and DØ experiments have worked to reach unprecedented levels of precision for many QCD observables. Thanks to the large dataset over 3 fb of integrated luminosity recorded by each experiment many important new measurements have recently been made public and will be summarized in this paper.

On the enhancement of the QCD running coupling in the noncontractible space and anomalous TeVatron and HERA data

We show that the existence of the fundamental ultraviolet cut-off (minimal scale) fixed by weak interactions enhances the QCD running coupling evaluated at one quantum loop level, starting at the scale in the vicinity of the cut-off. The enhancement of the QCD running coupling could completely explain the observed anomalous TeVatron and HERA data. The QCD in the noncontractible space is not an ...

WZ production at hadron colliders: Effects of nonstandard WWZ couplings and QCD corrections.

The process p p (−) → W±Z + X → `1 ν1`2 `2 + X is calculated to O(αs) for general C and P conserving WWZ couplings. At the Tevatron center of mass energy, the QCD corrections to WZ production are modest. At Large Hadron Collider (LHC) energies, the inclusive QCD corrections are large, but can be reduced significantly if a jet veto is imposed. Sensitivity limits for the anomalous WWZ couplings a...
