We illustrate one-loop weak corrections to three-jet production in $e^+e^-$ at $\sqrt{s}=M_Z$, to the production of a $Z$ or $\gamma$ in association with a hard jet at hadron colliders and to the production cross section of two $b$-jets at…

In models with an enhanced coupling of the Higgs boson to the bottom quark, the dominant production mechanism in hadronic collisions is often the partonic sub-process, bg ->bH. We derive the weak corrections to this process and show that…
