Summary
A definite length scale in Quantum Electrodynamics without a bare mass can only be induced by a coupling with another system. This problem is studied in a model consisting of one charged « neutrino » field and charged strongly interacting particle fields. A criterion is derived which is similar to the principle of extremalization of the energy in Mechanics. The approximation used allows only the conclusion that the ratio between the lepton mass and the strongly interacting particle masses is not of zeroth order in the renormalized electromagnetic coupling. constant.
Riassunto
Nell’elettrodinamica quantistica con massa nuda zero, si può indurre uua scala di lunghezze deflnita solo con l’accoppiamento ad un altro sistema. Si studia il problema su un modello costituito da un campo di« neutrini » carico e da campi di particelle cariche fortemente interagenti. Si ricava un criterio simile all’estrazione dell’energia in meccanica. L’approssimazione usata permette solo la conclusione che il rapporte tra la massa del leptone e le masse delle particelle fortemente interagenti non è d’ordine zero nella costante d’accoppiamento elettromagnetico rinormalizzata.
