Charge properties of the weak decay interactions of the new particles

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Relations and inequalities are given-which can be verified by experiment-between the transition probabilities of different decaymodes of new particles and light hyperfragments. In particular resstrictions are found for the relative probabilities of the different decay modes of charged ɛ-particles, for the relative probability of the Τ and of the ǵt-decays, and for the different mesonic decay modes of the lightest λ0-nuclei. These restrictions follow from the hypothesis that the weak decay interactions transform in charge space as the component, which satisfies charge conservation, of a spherical tensor of rank 1/2.

Riassunto

Vengono date delle relazioni e delle disuguaglianze tra le probabilità di transizione di differenti modi di decadimento di nuove particelle e di iperframmenti leggeri, che sono suscettibili di verifica sperimentale. In particolare: vengono trovate delle limitazioni per le probabilità relative dei diversi modi di decadimento dei ɛ carichi, per le probabilità relative dei decadimenti Τ e ǵt e per i differenti modi di decadimento dei nuclei λ0 più leggeri. Queste limitazioni seguono dall’ipotesi che l’interazione debole di decadimento si trasformi come la componente, richiesta dalla conservazione della carica, di un tensore sferico di ordine 1/2.
