Full NLO corrections to 3-jet production and R32 at the LHC

Understand

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 $\mathcal{O}(\alpha_s^n\alpha^m)$ with $n+m=3$ and $n+m=4$.
• This includes in particular also subleading Born contributions of electroweak origin, as well as electroweak virtual and QED real-radiative corrections.
• As an application we present results for the three- over two-jet ratio $R_{32}$.
