Note on the coupling of the technidilaton to the weak bosons

In this note, we study the coupling of the technidilaton to the weak bosons. We consider two cases: (1) The dilaton directly couples to the weak bosons in a similar way as in the standard model. (2) The coupling in question is effectively induced only through the technifermion loops. In both cases, we find that the coupling is essentially determined by the mass-squared of the weak bosons over the dilaton decay constant.
