Sažetak
The gamma -> 3 pi form factor was calculated
in a simple--minded constituent model with a constant quark mass
parameter, as well as in the Schwinger-Dyson approach.
The comparison of these and various other
theoretical results on this anomalous process,
as well as the scarce already available data
(hopefully to be supplemented by more accurate CEBAF data),
seem to favor Schwinger--Dyson modeling which would
yield relatively small low--momentum values of
the constituent (dynamically dressed) quark mass function.
