Operator of Sign of Energy

Abstract

In this paper we have defined what we call sign operator of energy in the Dirac theory. We have shown the analogy between this operator with the helicity operator. That has lead us to a signification of the sign of the energy.

Operator of Sign of Energy : Toward a Consequence

“…E is the projection in the direction of the energy vector E of the spin operator. Let us call the eigenvalues of this operator "enginity" and this operator the "enginity operator" [4]. Therefore there is the probabilities of the particle of having the positive enginity + 2 or the negative enginity − 2 .…”
