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

Christian W. Bauer, Nicolas Ferland, Bryan R. Webber

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 equatio…
