We consider a Hamiltonian describing the weak decay of the massive vector boson Z0 into electrons and positrons.

We show that the spectrum of the Hamiltonian is composed of a unique isolated ground state and that the spectrum below the boson mass is purely absolutely continuous.

This is joint work with Jeremy Faupin and Jean-Claude Guillot.
