Multiplet
In physics, multiplet can mean: * A group of related spectral lines * A group of related subatomic particles The best known example is a spin multiplet, which is a group representation of an SU(2) subgroup of the Lorentz algebra. For example, a spin singlet is a trivial representation, a spin doublet is a fundamental representation and a spin triplet is a vector representation. In other cases, the term ''multiplet'' usually refers to the fundamental representation of a gauge algebra. For example, in QCD, quarks are in a multiplet of SU(3). ==See also==
*Hypercharge *Isospin *Multiplicity (chemistry)
