# Electroweak corrections to diphoton plus jets

## TL;DR

This paper computes next-to-leading order electroweak corrections for diphoton plus jets production at the LHC, revealing significant effects on differential distributions and total cross sections, with implications for precision measurements.

## Contribution

It provides a fully automated calculation of electroweak corrections for diphoton plus jets production, including photon induced processes and subleading contributions.

## Key findings

- Electroweak corrections modify total cross sections by up to 3%.
- Substantial corrections are observed in differential distributions, reaching tens of percent.
- Photon induced processes are negligible, but subleading contributions can be significant without proper cuts.

## Abstract

We calculate the next-to-leading order electroweak corrections to the production of a photon pair in association with zero, one and two jets at the LHC. We use GoSam and Sherpa to obtain the results in a fully automated way. For a typical set of fiducial cuts the electroweak corrections lead to a modification of the total cross section of up to 3 per cent, depending on the jet multiplicity. We find substantial contributions in differential distributions, leading to tens of per cent corrections for phase space regions within the reach of the LHC. Furthermore we investigate the importance of photon induced processes as well as subleading contributions. Photon induced processes are found to be negligible, subleading contributions can have a sizeable impact however they can be removed by appropriate phase space cuts.
