It is the first time that the number of jets is not explicitly restricted to one or two, thus increasing the sensitivity to new signals. Instead, a balance between the most energetic jet and the missing transverse momentum is required, thus selecting mono-jet-like final states. Collider searches for Dark Matter have typically used signal models employing effective field theories (EFTs), even when comparing to results from direct and indirect detection experiments, where the difference in energy scale renders many such comparisons invalid. The thesis features the first robust and comprehensive treatment of the validity of EFTs in collider searches, and provides a means by which the different classifications of Dark Matter experiments can be compared on a sound and fair basis. 410 0$aSpringer Theses, Recognizing Outstanding Ph.D. Research,$x2190-5053 606 $aParticles (Nuclear physics) 606 $aQuantum field theory 606 $aCosmology 606 $aGravitation 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 $aClassical and Quantum Gravitation, Relativity Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/P19070 615 0$aParticles (Nuclear physics) 615 0$aQuantum field theory. 615 0$aCosmology. 615 0$aGravitation. 615 14$aElementary Particles, Quantum Field Theory. 615 24$aCosmology. 615 24$aClassical and Quantum Gravitation, Relativity Theory. 676 $a530.072 700 $aSchramm$b Steven$4aut$4http://id.loc.gov/vocabulary/relators/aut$0825015 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910155332203321 996 $aSearching for Dark Matter with the ATLAS Detector$91835136 997 $aUNINA
