Measurements of the branching ratios of top quark decays into leptons and jets using events with tt¯ (top antitop) pairs are reported. Events were recorded with the ATLAS detector at the LHC in pp collisions at a center-of-mass energy of 7 TeV. The collected data sample corresponds to an integrated luminosity of 4.6 fb-1. The measured top quark branching ratios agree with the Standard Model predictions within the measurement uncertainties of a few percent.

Abstract

Measurements of the branching ratios of top quark decays into leptons and jets using events with tt¯ (top antitop) pairs are reported. Events were recorded with the ATLAS detector at the LHC in pp collisions at a center-of-mass energy of 7 TeV. The collected data sample corresponds to an integrated luminosity of 4.6 fb-1. The measured top quark branching ratios agree with the Standard Model predictions within the measurement uncertainties of a few percent.
