Complex sentence: RWEs for particles of spin higher than 1/2 can be constructed heuristically from the Dirac equation, by forming symmetric products of Dirac spinors to form a multicomponent spinor describing a particle of the appropriate spin.
Split into simpler sentences: RWEs for particles of spin higher than 1/2 can be constructed heuristically from the Dirac equation. One approach is to form symmetric products of Dirac spinors to form a multicomponent spinor describing a particle of the appropriate spin.
