On the properties of spin 2 particles

Summary

A theory of spin 2 particles has been worked out. The wave equations are of first order and a symbolic approach which is developed permits easy computation of quantities of physical interest. An interesting application of the sum rules for spin 2 particles is the calculation of the Coulomb scattering in relativistic Born approximation. The theory is also applied to calculate the decay of a spin 2⁺ particle into three pseudoscalar particles and into two Dirac particles. The bearing of the decay calculations on the spin 2⁺ hypothesis for the K-meson is discussed.

Riassunto

La teoria delle particelle di spin 2 viene messa sotto forma più elegante per mezzo di un metodo simbolico simile a quello di Dirac per l’elettrone. Si esaminano e si discutono alcuni processi, tra cui lo scattering su di un potenziale di Coulomb e se ne calcolano le sezioni d’urto.
