 Searches for new physics with leptons and invisible particles at the ATLAS experiment at the LHC / Gallardo, Gabriel The Standard Model of Particle Physics (SM), while successful at describing almost all subatomic phenomena observed to date, has some glaring open questions: the Higgs boson mass is unstable at high energies, there is no dark matter candidate, and the prediction and measurement of $(g − 2)_\mu$ ar [...] CERN-THESIS-2021-139 - 194 p.
