A model of the basic particles and forces featuring six quarks, three charged leptons, three massless neutral leptons and four fundamental force carrying bosons. The twelve fermions are arranged into three generations, while the bosons serve to explain the electromagnetic interaction plus the strong and weak nuclear forces (and the Higgs mechanism). Do NOT use this tag for the standard model of cosmology, etc..

The Theories of the Standard Model
The theories combined by the Standard Model of particle physics are:
- quantum-chromodynamics of the strong interaction.
- electroweak-theory of the electromagnetic and weak interactions. (Note that electromagnetism alone is described by quantum-electrodynamics). This is along with an additional higgs-mechanism to explain the Electroweak symmetry breaking (why do the W & Z bosons have mass?)
The Standard Model, describes all experimentally known fundamental interactions, except for gravity, which is classically described by general-relativity.
A candidate for a consistent framework that accommodates the physics of the Standard Model with gravitation is string-theory. Other shortcomings of the Standard Model include the vastly large number of dimensionless constants, the need for renormalisation, etc.
