Top Quark Production Cross Section
The production rate for top quarks at the Fermilab Tevatron is presented using the exact order α 3 s corrected cross section and the resummation of the leading soft gluon corrections in all orders of perturbation theory.
متن کاملTop Quark Pair Production Cross Section at the Tevatron
Top quark pair production cross section has been measured at the Tevatron by CDF and DØ collaborations using different channels and methods, in order to test standard model predictions, and to search for new physics hints affecting the tt̄ production mechanism or decay. Measurements are carried out with an integrated luminosity of 1.0 to 2.0 fb, and are found to be consistent with standard model...
متن کاملTop Quark Production Cross Section at the Tevatron
An overview of the preliminary results of the top quark pair production cross section measurements at a center-of-mass energy of 1.96 TeV carried out by the CDF and DØ collaborations is presented. The data samples used for the analyses are collected in the current Tevatron run and correspond to an integrated luminosity from 360 pb −1 up to 760 pb −1 .
متن کاملTop Quark Production Cross Section at the Tevatron
Since the discovery of the top quark by the CDF and DØ Collaborations 1, Tevatron remains the world’s only experimental facility where it’s properties can be investigated. In pp̄ collisions top quarks are dominantly produced in pairs via strong interaction. Depending on the decay modes of the W -bosons, one expects three distinctive event topologies from the tt̄ → WbWb̄ signal: a di-lepton final s...
متن کاملPerturbative Gluon Resummation of the Top-quark Production Cross Section
We present a calculation of the total cross section for top quark production based on a new perturbative resummation of gluon radiative corrections to the basic QCD subprocesses. We use Principal Value Resummation to calculate all relevant large threshold corrections. Advantages of this method include its independence from arbitrary infrared cutoos and speciication of the perturbative regime of...
