Towards an unbiased determination of parton distributions with QED corrections

Understand

Electroweak corrections to hadron collider processes become relevant at the level of precision reached by present-day LHC experiments.

• We provide a preliminary discussion of the impact of electroweak corrections to parton distributions, concentrating on electrodynamics corrections to parton evolution equations, and showing a preliminary assessment of their impact.
• Furthermore, we determine the parton distribution function of the photon from deep inelastic scattering data using the NNPDF methodology.
