  The discovery of the Higgs boson, ten years ago, was a milestone that opened
the door to the study of a new sector of fundamental physical interactions. We
review the role of the Higgs field in the Standard Model of particle physics
and explain its impact on the world around us. We summarize the insights into
Higgs physics revealed so far by ten years of work, discuss what remains to be
determined, and outline potential connections of the Higgs sector with unsolved
mysteries of particle physics.
