It corresponds to Demeur's formula for electron in QED. The energy of this state, describing effective particle mass, is computed by solving the Schwinger-Dyson equation. As application, we investigate the effective mass squared at the threshold of the tree-level instability, $B \\to B_c = m^2/e$, and show that it is positive. In this way the stability of the W-boson spectrum is established.
