The matrix element method has been extensively used for the analysis of top-quark and W-boson physics at the Tevatron but in general without dedicated treatment of initial-state QCD radiation. At the LHC, the increased center-of-mass energy leads to a significant increase in the amount of QCD radiation, which makes it mandatory to carefully account for its effects. We here present several methods for inclusion of QCD radiation effects in the matrix element method and apply them to mass determination in the presence of multiple invisible particles in the final state. We demonstrate significantly improved results compared to the standard treatment.
