Searches for $t\bar{t}H$ and flavour-changing $t\to Hq$ productions in multileptonic final states with the ATLAS detector / Wolff, Robert
After the Higgs boson discovery at the Large Hadron Collider (LHC), the focus of experimental particle physics is on the measurement of its interaction with other particles of the Standard Model (SM) [...]

Exploiting the ATLAS detector in a search for stop squark in a compressed mass spectrum using the Higgs boson / D'Amen, Gabriele
In past decades, experimental and theoretical efforts offered several reasons to believe that the Standard Model of particles (SM) is nothing more than an effective low-energy approximation of a more fundamental theory [...]

Study of the Higgs boson production in association with a top quark pair with the ATLAS experiment at the LHC / Dumitriu, Ana Elena
The scientific work presented in this thesis is based on proton proton collision produced, at 13 TeV in the center of mass, created by the Large Hadron Collider (LHC) and recorded between 2015 and 2017 by the ATLAS detector [...]

$b$-Tagging and Evidence for the Standard Model $H \to b\bar{b}$ Decay with the ATLAS Experiment / Bell, Andrew Stuart
The observation of a new particle consistent with the Standard Model Higgs boson by the ATLAS and CMS experiments in 2012 heralded a new era in the understanding of the Standard Model [...]

Measurements of isolated-photon production inclusively and in association with jets at \boldmath$\sqrt{s}=13$~TeV with the ATLAS detector / Cueto Gomez, Ana Rosario
Measurements of prompt-photon production at the Large Hadron Collider provide a handle on the gluon density in the proton by means of the Compton scattering and can be used to constrain the gluon density function inside the proton [...]

Measurements of differential $t$-channel single top-quark production cross-sections in proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector / Seema, Pienpen
Proton-proton collision data at a centre-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, corresponding to an integrated luminosity of 20.2 fb$^{-1}$, are used to measure absolute and normalised differential cross-sections of single top quarks produced in the $t$-channel [...]

Differentiating Top-Quark - Photon Coupling: Inclusive and Differential Cross-Section Measurements of Top-Quark Pair Production in Association with a Photon in the Single Lepton Channel in pp Collisions Data at $\sqrt{s}$ = 8TeV with the ATLAS Experiment / Atlay, Naim Bora
This thesis presents measurements of inclusive and differential production cross sections of top- anti-top-quark pairs in association with an additional prompt photon ($\sigma_{t\bar{t}\gamma}$) in the single lepton final state at the LHC analysing data recorded by the ATLAS detector [...]
