Relativistic two and three-particle states

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Two-particle states transforming according to standard representations of the inhomogeneous Lorentz group are constructed which, in the centre-of-mass system, are eigenstates of orbital and spin angular momentum operators. The connection between these and helicity states is derived and a recoupling coefficient for three-particle states in the former scheme found.

Riassunto

Si costruiscono stati di due particelle, che si trasformano secondo le rappresentazioni normali del gruppo di Lorentz non omogeneo e che, nel sistema del centro di massa sono autostati degli operatori del momento angolare orbitale e di spin. Si deduce la connessione fra questi e gli stati di elicità e si trova un coefflciente di riaceoppiamento per gli stati di tre particelle nello schema precedente.
