| Abstract: | It is shown that massive fermions have their helicity flipped on account of their interaction with an electromagnetic field described by Podolsky’s generalized electrodynamics. Massless fermions, in turn, seem to be unaffected by the electromagnetic field as far as their helicity is concerned. |
