Constraints on composite models from leptonic flavour-changing decays

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

We analyse a composite model of leptons based on the inclusion of heavy vector weak isodoublets. Diagonalization of the mass matrix gives rise to flavour-changing processes and contributions to anomalous magnetic moments. Nonobservation of such processes can give some constraints on compositeness energy scale.

Riassunto

In questo lavoro si analizza un modello composto di leptoni, basato sull’introduzione di doppietti vettoriali pesanti. La diagonalizzazione della matrice di massa dà luogo a processi con cambiamento di sapore e a termini di momento magnetico anomalo. I limiti sperimentali di tali processi possono fornire vincoli sulla scala di energia, alla quale si potrebbe evidenziare la struttura interna dei leptoni.
