  We present search results based on next-to-leading order predictions for the
pair production of color-adjoint leptons at the LHC. Quantum effects are
sizable, dominated by pure QCD corrections, and sensitive to threshold effects.
We illustrate the stabilization of scale dependences and confirm an excellent
agreement between fixed-order and multi-jet predictions for representative
distributions. Finally, we examine the trademark collider signatures of
leptogluon pairs. Based on the CMS leptoquark search we derive a mass bound of
1.2-1.3 TeV for charged leptogluons, significantly improving the constraints
available in the literature.
