Measurement of the top quark charge at the ATLAS detector

Creators

Description

We have investigated the possibility of reconstructing the top quark charge through measurement of its decay product charges at the ATLAS detector. Verification of the hypothesis about alternative interpretation of top-quark experimental data has been considered as well. The method of 'semileptonic B-meson decay' was applied for reconstructing the b-jet charge. A statistical significance of more than 5σ can be achieved using this method after analyzing 1 fb-1 of tt bar - pairs data. The analysis was carried out with HERWIG and PYTHIA generators and using the GEANT4 detector simulation package
