A study of τ-meson decay

  • Published:
Il Nuovo Cimento (1943-1954)

Summary

The distribution of the π-mesons in the decay of the τ-meson is studied, and approximate expressions for the matrix elements are found. Thus one can justifyDalitz’ results, in which the relativistic corrections are also introduced. The comparison with experiment is done taking into account the charges of the π-mesons; the experimental data, however, are still too poor to give any information about parity and spin of the τ-meson.

Riassunto

Si studia la distribuzione dei mesoni π nel decadimento del τ e si trovano espressioni approssimate per gli elementi di matrice. Si possono così giustificare i risultati diDalitz, in cui vengono anche introdotte le correzioni relativistiche. Il confronto coll’esperienza è effettuato tenendo conto delle cariche dei π; tuttavia i dati sperimentali sono ancora troppo scarsi per dare una qualche informazione sulla parità e sullospin del τ.
