Determination of the pole and MSbar masses of the top quark from the ttbar cross section

TL;DR

This paper extracts the top quark mass from the ttbar production cross section using advanced QCD calculations, providing an alternative measurement method and comparing results with direct measurements at the Tevatron.

Contribution

It introduces a novel approach to determine the top quark mass via cross section analysis using higher-order QCD calculations, complementing direct measurement techniques.

Findings

Top quark pole mass and MSbar mass are extracted from experimental data.

Results are consistent with current Tevatron average top quark mass.

The method provides an independent cross-check of top quark mass measurements.

Abstract

We use higher-order quantum chromodynamics calculations to extract the mass of the top quark from the ttbar cross section measured in the lepton+jets channel in ppbar collisions at sqrt(s)=1.96 TeV using 5.3 fb-1 of integrated luminosity collected by the D0 experiment at the Fermilab Tevatron Collider. The extracted top quark pole mass and MSbar mass are compared to the current Tevatron average top quark mass obtained from direct measurements.
