Study of the Higgs boson properties in $H \to ZZ^* \to 4l$ decay channel with the ATLAS detector at LHC using data recorded at $\sqrt{s} = 8 - 13$ TeV / Mancini, Giada
The Higgs Boson is the keystone particle of the Standard Model (SM): its existence explains the massive nature of matter and makes the theory re-normalizable [...]

Measurements of charge and $CP$ asymmetries in $b$-hadron decays using top-quark events collected by the ATLAS detector in $pp$ collisions at $\sqrt{s}=8$ TeV / Kempster, Jacob Julian
Same- and opposite-sign charge asymmetries are measured in lepton+jets $t\bar{t}$ events in which a $b$-hadron decays semileptonically to a soft muon, using data corresponding to an integrated luminosity of 20.3 fb$^{-1}$ from proton-proton collisions at a centre-of-mass energy of $\sqrt{s}=8$ TeV c [...]

Contribution to the energy and time measurement of electrons and photons in the ATLAS experiment and search for dark matter production in association to a Higgs boson. / Lopez Solis, Alvaro
The discovery of a particle consistent with a Standard Model (SM) Higgs boson in 2012 by the ATLAS and CMS collaborations has opened up new possibilities in searches for physics beyond the SM (BSM) [...]
