Abstract.

We study the decays into six quarks of off-shell pairs of \(W^\pm\) bosons produced in electron-positron annihilations, through the \({\cal O}(\alpha_s^2)\) order in the strong coupling constant. We give explicit helicity amplitude formulae. We present numerical results in the context of phenomenological analyses of relevance at LEP2 and future Linear Colliders: such as \(M_W\) determinations, New Physics and Higgs searches.
