SummaryInvariance of the S-matrix of ordinary quantum electrodynamics under gauge transformations of the electromagnetic field is demonstrated explicitly. The behavior of the S-matrix of stochastic quantum electrodynamics is examined under gauge transformations of the mean value electromagnetic fieldAπ(x;L). This stochastic S-matrix is not strictly gauge invariant, to the same degree that the theory fails to satisfy micro-causality.RiassuntoSi dimostra esplicitamente l’invarianza delia matriceS… CONTINUE READING
