Scalar leptoquark pair production at hadron colliders

We revisit scalar leptoquark pair production at hadron colliders. Apart from QCD contributions, we include the lepton t-channel exchange diagrams relevant in the light of the recent B-flavor anomalies. We evaluate all contributions at next-to-leading order in QCD and resum, in the threshold regime, soft-gluon radiation at next-to-next-to-leading-logarithmic accuracy. All corrections are found equally relevant. Our predictions consist of the most precise leptoquark cross section calculations available to date and are necessary for the best exploitation of leptoquark LHC searches.
