Gauge-invariant three-boson vertices in the standard model and the static properties of the<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>W</mml:mi></mml:math>
We use the $S$-matrix pinch technique to derive to one-loop order gauge-independent $\ensuremath{\gamma}{W}^{+}{W}^{\ensuremath{-}}$ and $Z{W}^{+}{W}^{\ensuremath{-}}$ vertices in the context of the standard model, with all three incoming momenta off shell. We show that the $\ensuremath{\gamma}{W}^{+}{W}^{\ensuremath{-}}$ vertex so constructed is related to the gauge-independent $W$ self-energy, derived by Degrassi and Sirlin, …
