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. The book summarises the analysis of
the data collected with the ATLAS detector in 2015 and 2016. In
order to better differentiate between signals and backgrounds,
exclusive taggers of top quark and Higgs boson were developed and
optimised for VLT signals. These efforts improved the sensitivity
by roughly 30%, compared to the previous analysis. The analysis
outcomes yield the strongest constraints on parameter space in
various BSM theoretical models. In addition, the book addresses
detector operation and the evaluation of tracking performance.
These efforts are essential to properly collecting dense events and
improving the accuracy of the reconstructed objects that are used
for particle identification. As such, they represent a valuable
contribution to data analysis in extremely dense environments.
