Determination of the top quark mass from the $t\bar t$ cross section measured by CMS at $\sqrt{s} = 7$ TeV

TL;DR

This paper determines the top quark mass by comparing measured top pair production cross sections at 7 TeV with advanced QCD predictions, using CMS data from 2011, providing a novel method for mass extraction.

Contribution

It introduces a method to extract the top quark mass from cross section measurements using higher-order QCD predictions in both pole and ar schemes.

Findings

Top quark mass values obtained consistent with previous measurements.

Demonstrated the viability of using cross section data for mass determination.

Enhanced precision in top quark mass measurement techniques.

Abstract

Higher-order QCD predictions are used to extract the top quark mass, both in the pole and in the $\bar{\mathrm{MS}}$ scheme, from the top quark pair production cross section measured in the dilepton final state. The analysed dataset corresponds to an integrated luminosity of 1.14 fb$^{-1}$ collected by the CMS experiment in 2011 in proton-proton collisions at $\sqrt{s} = 7$ TeV.
