Measurements of ttbar production cross-section with D0 experiment

TL;DR

This paper reports measurements of the top-antitop quark pair production cross-section at Fermilab's Tevatron, using 1 fb^{-1} of data, which align with Standard Model predictions within a 10% uncertainty.

Contribution

First measurements of ttbar production cross-section in proton-antiproton collisions at 1.96 TeV with D0, including lepton + jets and dilepton channels, using 1 fb^{-1} of data.

Findings

Measured cross-section compatible with Standard Model

Uncertainty close to theoretical prediction (~10%)

Results support current top quark production models

Abstract

The recent measurements of the top anti-top quark pair production cross-section in proton antiproton collisions at sqrt{s}=1.96 TeV in lepton + jets and dilepton (including tau lepton) channels are presented. These measurements are based on 1 fb^{-1} of data collected with the DO experiment at the Fermilab Tevatron collider. The measured values are compatible with the standard model prediction and have the uncertainty close to the uncertainty of the theoretical prediction ~10%.
