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. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aParticle acceleration 606 $aNuclear physics 606 $aHeavy ions 606 $aParticles (Nuclear physics) 606 $aQuantum field theory 606 $aParticle Acceleration and Detection, Beam Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P23037 606 $aNuclear Physics, Heavy Ions, Hadrons$3https://scigraph.springernature.com/ontologies/product-market-codes/P23010 606 $aElementary Particles, Quantum Field Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P23029 615 0$aParticle acceleration. 615 0$aNuclear physics. 615 0$aHeavy ions. 615 0$aParticles (Nuclear physics) 615 0$aQuantum field theory. 615 14$aParticle Acceleration and Detection, Beam Physics. 615 24$aNuclear Physics, Heavy Ions, Hadrons. 615 24$aElementary Particles, Quantum Field Theory. 676 $a539.72167 700 $aYamaguchi$b Daiki$4aut$4http://id.loc.gov/vocabulary/relators/aut$0839019 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910350220203321 996 $aSearch for New Phenomena in Top-Antitop Quarks Final States with Additional Heavy-Flavour Jets with the ATLAS Detector$91873781 997 $aUNINA
