SUMMARY
A multiplet refers to a grouping of elementary particles that arise from the representation theory of Lie Algebras. In quantum mechanics, angular momentum states are organized into multiplets labeled by the quantum number j, and this concept extends to other symmetry groups beyond SU(2), which introduce additional labels. Understanding multiplets is crucial for grasping the underlying symmetries in particle physics. Recommended literature includes Greiner's "Quantum Mechanics - Symmetries" for a comprehensive overview.
