Precision predictions for exotic lepton production at the Large Hadron Collider

Résumé

We calculate total and differential cross sections for the pair production, at the Large Hadron Collider, of exotic leptons that could emerge from models with vector-like leptons and in Type-III seesaw scenarios. Our predictions include next-to-leading-order QCD corrections, and we subsequently match them with either parton showers, or threshold resummation at the next-to-next-to-leading logarithmic accuracy. Our results show an important increase of the cross sections relative to the leading-order predictions, exhibit a distortion of the shapes for various differential distributions, and feature a significant reduction of the scale uncertainties. Our predictions have been obtained from new {\sc FeynRules} model implementations and associated UFO model libraries. This completes the set of next-to-leading-order implementations of new physics models featuring extra leptons that are publicly available on the {\sc FeynRules} model database.
