On scale transformations

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

Invariance against scale transformation was used byW. Heisenberg (1) to define a lepton number. Some properties of this transformation are more easily investigated with scalar fields, the mass dependence of which is known. For the scalar fields and the harmonic-oscillator, some properties of the infinitesimal transformation are listed here.

Riassunto

Per definire un numero leptonico,W. Heisemberg si è servito dell’invarianza rispetto alla trasformazione scalare. Alcune proprietà di tale trasformazione sono esaminate in maniera più semplice facendo uso di campi scalari di cui sia nota la dipendenza dalla massa. Si elencano qui, per i campi scalari e per l’oscillatore armonico, alcune proprietà della trasformazione infinitesimale.
