Resonant Single BSM Particle Production at the LHC using Lepton PDFs — •Jonas Botz, Saurabh Nangia, Yong Sheng Koay, Philip Bechtle, Klaus Desch, Herbert Dreiner, and Manuel Drees — Physikalisches Institut der Rheinischen-Friedrich-Wilhelms-Universität Bonn

Many new physics scenarios require particles (leptoquarks) that couple to a vertex at which both leptons and quarks interact. Indeed, leptoquark searches have received considerable interest at the LHC. Recently, however, a new search strategy has been proposed. Combining QCD and QED effects, there is a non-zero probability to find leptons with a certain momentum inside the proton, described by the lepton parton distribution functions (PDFs). Such PDFs have recently been calculated for the first time. This allows us to study resonant leptoquark production at the LHC. In the following phenomenological study, a search strategy is analysed for resonant leptoquark production at the LHC using the one lepton and one jet final state. After identifying the most relevant backgrounds and discussing cuts, parameter space diagrams of minimal leptoquark models are shown to demonstrate the LHC sensitivity.
