Full NLO corrections to 3-jet production and $$\mathbf {R_{32}}$$ R32 at the LHC
Abstract We present the evaluation of the complete set of NLO corrections to three-jet production at the LHC. To this end we consider all contributions of $$\mathcal{{O}}(\alpha _s^n\alpha ^m)$$ O(αsnαm) with $$n+m=3$$ n+m=3 and $$n+m=4$$ n+m=4 . This includes in particular also subleading Born cont...
