Description

This study focuses on the statistical analysis of the ongoing $t\overline{t}$ resonance search at ATLAS, which aims at searching for new heavy particles decaying to a top quark pair in fully hadronic final state with full Run 2 data. In this study, BumpHunter is employed to search for deviation from a smoothly falling background prediction, while Frequentist CLs method is used to set upper limit for cross section in absence of significant deviation.
