Abstract
The mass formula summation/sub J/(- 1)/sup 2J/(2J + 1) m/sub J/ /sup 2/ = 0 is derived for a very general class of interactions with spontaneously broken supersymmetry. It shows the vanishing of the graded trace of the square of the mass operator, with m/sub J/ the mass associated with a (real) field of spin J. This mass relation is shown to be true even in the presence of explicit breaking, provided it fulfills suitable requirements.
