The Large Hadron Collider (LHC) at CERN collides protons with unprecendeted high energy and intensity. Dedicated detectors, named ATLAS, CMS and LHCb, measure these collisions and attempt to reconstruct the stable, unstable and elusive particles that were produced therein. Most of the observed reactions can be described with particles and forces that are part of the well known Standard Model of particle physics. The goal of the LHC physics programme is to understand how the elementary particles can have mass (for example via the, so-called, Higgs mechanism), and to give insight into how the particles and forces behave when the energy is risen beyond everything every studied in the laboratory, energies as they occurred in the earliest moments of our universe. The Standard Model becoming unstable at these high energies, strong theoretical arguments favour the appearance of new phenomena. Astrophysical observations corroborate this perception. The colloquium will provide a journey through the most salient results obtained at the LHC and their impact on our understanding of particle physics.
