Is the Standard Model of particle physics complete?
So although the Standard Model accurately describes the phenomena within its domain, it is still incomplete. Perhaps it is only a part of a bigger picture that includes new physics hidden deep in the subatomic world or in the dark recesses of the universe.
What is the Standard Model of an atom?
The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make up the chemical elements, along with any other particles that cannot be broken down into any smaller pieces.
What is the Standard Model based on?
The Standard Model is a theory in particle physics which addresses three of the four known forces in Nature: electromagnetic force, weak nuclear force, and the strong nuclear force. The current formulation was finalized in the mid-1970s. The Standard Model is based on symmetry principles, such as rotation.
Is the Higgs Standard Model?
The Higgs boson is an elementary particle in the Standard Model of particle physics produced by the quantum excitation of the Higgs field, one of the fields in particle physics theory. In the Standard Model, the Higgs particle is a massive scalar boson with zero spin, no electric charge, and no colour charge.
Is Standard Model correct?
The Standard Model is a thing of beauty. It is the most rigorous theory of particle physics, incredibly precise and accurate in its predictions. Despite its great predictive power, however, the Standard Model fails to answer five crucial questions, which is why particle physicists know their work is far from done.
How many particles are there in the Standard Model?
17
The Standard Model consists of 17 fundamental particles. Only two of these – the electron and the photon – would have been familiar to anyone 100 years ago. They are split into two groups: the fermions and the bosons. The fermions are the building blocks of matter.
What are the components of the Standard Model?
The two components of the standard model are electroweak theory, which describes interactions via the electromagnetic and weak forces, and quantum chromodynamics, the theory of the strong nuclear force.

What has the Standard Model predicted?
The Standard Model does not predict the mass of the Higgs boson or the individual masses of any particles, but it does predict the ratio of the Z and W boson masses. Intriguingly, this is linked to the ratio of the weak and electromagnetic force strengths.
