The collider phenomenology of TeV-scale leptoquarks had a new twist recently. The precise extraction of lepton parton distribution functions based on the LUX method facilitated an additional leptoquark production mechanism, the resonant leptoquark production. After briefly reviewing and comparing different production mechanisms, I will present the first computation of next-to-leading order QCD and QED corrections to the resonant leptoquark production cross-section at the Large Hadron Collider. Various NLO K-factors, together with the theoretical uncertainties due to the renormalisation and factorisation scale variations and the limited knowledge of parton distribution functions will be shown. I will conclude with a discussion of the possibility to disentangle the flavor structure of leptoquark interactions by exploiting the interplay between different production channels.
