We sketch in simple terms the concept of the Higgs mechanism, and its importance in particle physics.
To the best of our knowledge, the world consists of only very few types of elementary particles, the smallest entities of matter, which are indivisible.
They are described successfully by the Standard Model (SM) of particle physics, a great scienti c achievement of the 20th century.
All phenomena observed so far with elementary particles are compatible with the SM, which made a large number of correct predictions.
However, there is one particle that the SM needs in order to work, which has not been safely observed yet: the famous Higgs particle.
The Large Hadron Collider at CERN near Geneva is intensively searching for it.
In December 2011 it reported rst hints of an observation, which have meanwhile been further substantiated, but a rigorous veri cation takes more time…
