Contribution
It provides updated measurements of top pair production cross sections across multiple decay channels at different energies, combining results from CMS and ATLAS.
Findings
Measured cross sections agree with theoretical calculations
Results cover multiple decay channels including tau modes
Updated measurements at 7 TeV and 8 TeV energies
Abstract
The most recent results on the measurements of (tt) production and cross sections at 7 TeV are presented. These are obtained using CMS [1] and ATLAS [2] data collected in 2011. Recent results on the tt production cross section at 8 TeV using 2012 CMS data are also presented. The tt inclusive cross sections are measured in the lepton+jets, dilepton and fully hadronic channels, including the tau-dilepton and tau+jets modes. The results are combined and confronted with precise theory calculations.
