Direct photon production and PDF fits reloaded

Campbell, John M., Rojo, Juan, Slade, Emma et al.

Understand

Direct photon production in hadronic collisions provides a handle on the gluon PDF by means of the QCD Compton scattering process.

In this work we revisit the impact of direct photon production on a global PDF analysis, motivated by the recent availability of the next-to-next-to-leading (NNLO) calculation for this process.
We demonstrate that the inclusion of NNLO QCD and leading-logarithmic electroweak corrections leads to a good quantitative agreement with the ATLAS measurements at 8 TeV and 13 TeV, except for the most forward rapidity region in the former case.
By including the ATLAS 8 TeV direct photon production data in the NNPDF3.1 NNLO global analysis, we assess its impact on the medium-x gluon.
