Beschreibung:
This book reports on the search for a new heavy particle, the Vector-Like Top quark (VLT), in the Large Hadron Collider (LHC) at CERN. The signal process is the pair production of VLT decaying into a Higgs boson and top quark (TT¿Ht+X, X=Ht, Wb, Zt). The signal events result in top-antitop quarks final states with additional heavy flavour jets.
Introduction.- The ATLAS Experiment at the Large Hadron Collider.- Reconstruction of physics objects.- Data and Event simulations.- Signal and background modeling.- Optimisations of heavy object tagging and event categorisation.- Analysis strategy.- Systematic uncertainties.- Statistical analysis.- Results.- Discussion.- Prospect.- Conclusion.
