Combining initial-state resummation with fixed-order calculations of electroweak corrections

Understand

We present a resummation of those double-logarithmically enhanced electroweak correction that arise in pp colliders because protons are not SU(2) singlets, by solving DGLAP equations in the full Standard Model.

• We then show how to match these results with those of fixed-order electroweak calculations.
• At a 100 TeV pp collider, contributions beyond order alpha are ~ 10% at partonic center-of-mass energies of a few TeV.
• These are mainly due to initial states with massive vector bosons.
