How LHC changed the way we think in Physics

Discoveries and measurements at the LHC impacted on particle physics in a broad variety of ways. On one side, the Higgs discovery confirmed the basic scenario for electroweak symmetry breaking, namely the Standard Model (SM). On the other, the absence of widely anticipated phenomena beyond the SM led to a major rethinking of the motivations for the existence of such new phenomena, as well as of the way searches for new physics are performed, and the ensuing constraints are interpreted. In parallel, precise measurements of a diverse variety of phenomena exposed new puzzles in our understanding of the SM dynamics, challenging established wisdom.
