Electroweak corrections to Z + 2 jets production at the LHC

TL;DR

This paper calculates electroweak radiative corrections to Z boson production with two jets at the LHC, showing small effects on total rates but significant impacts on distribution tails.

Contribution

It provides the first detailed computation of electroweak corrections for Z + 2 jets production using automated tools in the Standard Model.

Findings

Electroweak corrections are small for inclusive cross sections.

Corrections can be large in the tails of distributions.

Results are relevant for precision measurements at the LHC.

Abstract

We present results for the electroweak radiative corrections to the production of a leptonically decaying Z boson in association with two jets at the LHC. Tree-level and one-loop amplitudes have been obtained with the computer code Recola for the recursive generation of tree-level and one-loop amplitudes in the Standard Model. The one-loop integrals have been calculated with the tensor-integral library Collier. The electroweak corrections turn out to be small for inclusive cross sections but can become large in tails of distributions.
