Measurement of the top quark mass with the decay length method at the ATLAS experiment — •Christian Jung — TU Dortmund, Experimentelle Physik IV

The decay length method exploits the Lorentz boost of emerging B hadrons from top quark decays to determine the top quarks mass. Its main feature is the independence of the jet energy scale due to only requiring tracking information. The application to ATLAS data of √s= 7 TeV center of mass energy is presented.
