Abstract
Motivated by scaling considerations we formulate a theory of decay based on the Kemmer equation. We find that our theory (1) has a symmetry-breaking parameter of order 10-30% which agrees with experiment, (2) makes a definite testable prediction of a kinematic zero at in the "effective" scalar form factor, and (3) yields a modified Callan-Treiman relation which improves agreement with experiment.
