This work discusses properties of a recently published weak interactions theory which is derived from a Lagrangian density Lw. This theory depends on the experimentally confirmed massive neutrino. The interaction which is carried by an appropriate mediating field is consistent with the Fermi coupling constant of weak interactions GF. Its results prove the existence of a vector term V and an axial vector term A in a description of weak interactions processes and of their associated parity nonconservation. An analysis of the weak interactions Lagrangian density Lw shows similarity and differences between the theoretical structure of electrodynamics and that of weak interactions.
