The concept of mass in particle physics — •Georg Weiglein — DESY, Hamburg

The recent discovery of a particle with properties that are compatible with a Higgs boson as postulated in the Standard Model of particle physics marks a breakthrough in the quest for understanding how elementary particles can acquire the property of mass. The concept of the mass of an elementary (point-like) particle is discussed, and possible mechanisms for generating masses of elementary particles within and beyond the Standard Model of particle physics are highlighted. The conceptual differences between the masses of elementary and composite particles are pointed out.
