Top quark pair production cross-section results at LHC in final states with tau or no leptons

TL;DR

This paper reports measurements of the top quark pair production cross section at the LHC using 7 TeV collision data, focusing on final states with a tau lepton or no leptons, providing insights into top quark production in different decay channels.

Contribution

It presents new measurements of the top quark pair production cross section in specific final states with tau leptons or no leptons, expanding the understanding of top quark decay modes.

Findings

Measured cross sections in tau and no-lepton channels.

Results are consistent with Standard Model predictions.

Provides data for testing top quark production models.

Abstract

ATLAS and CMS measured the top quark pair production inclusive cross section using proton-proton collision data collected at 7 TeV c.m. energy at the LHC during the year 2011 in several channels. This article presents the measurements of the cross section using selections of top quark pair production events with one hadronically decaying {\tau} lepton or no leptons at all.
