Based on 2015 and 2016 ATLAS proton-proton collision data, this thesis presents searches for the supersymmetric partner of the top quark, for Dark Matter, and for DarkEnergy, in signatures with jets and missing transverse energy. Muon detection is key to some of the most important LHC physics results, including the discovery of the Higgs boson and the measurement of its properties. The efficiency with which muons can be detected with the ATLAS detector is measured using Z boson decays. The performance of high-precision Monitored Drift Tube muon chambers under background rates similar to the ones expected for the High Luminosity-LHC is studied. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aElementary particles (Physics) 606 $aQuantum field theory 606 $aCosmology 606 $aMathematical physics 606 $aElementary Particles, Quantum Field Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P23029 606 $aCosmology$3https://scigraph.springernature.com/ontologies/product-market-codes/P22049 606 $aTheoretical, Mathematical and Computational Physics$3https://scigraph.springernature.com/ontologies/product-market-codes/P19005 615 0$aElementary particles (Physics). 615 0$aQuantum field theory. 615 0$aCosmology. 615 0$aMathematical physics. 615 14$aElementary Particles, Quantum Field Theory. 615 24$aCosmology. 615 24$aTheoretical, Mathematical and Computational Physics. 676 $a539.72 676 $a539.72167 700 $aKöhler$b Nicolas Maximilian$4aut$4http://id.loc.gov/vocabulary/relators/aut$01061176 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910349509203321 996 $aSearches for the Supersymmetric Partner of the Top Quark, Dark Matter and Dark Energy at the ATLAS Experiment$92517786 997 $aUNINA
