Description
After the discovery of the Higgs Boson, the predictions of the Standard Model of particle physics can
be extrapolated without inconsistencies all the way up to the Planck mass. Despite this tremendous
success, we still remain in the dark about many open puzzles. Why is the weak interaction much
stronger than gravity? What is the nature of Dark Matter? Are the strong, weak and electromagnetic
forces a lower-energy manifestation of one single fundamental interaction? A possible solution to these
questions is provided by Supersymmetry. The key assumption behind many natural supersymmetric
models is that the masses of the gluinos, the top squarks and the higgsinos are near the TeV scale, thus
within the LHC reach. In this presentation, I will introduce some of the theoretical and phenomenological
arguments that motivate the quest for Supersymmetry. I will then outline how I searched for
the above-mentioned particles using LHC Run-2 data collected by the ATLAS experiment. Finally, I
will conclude with my vision of the future prospects at the LHC.
