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.
The Theories of the Standard Model
QCD and QED as extended to include the weak force are the descriptive theories of the standard model.
Other Standard Models
Cosmology and Stellar Physics also have baseline models sometimes described as "the Standard Model"
