The Matrix Element Method and QCD Radiation

Alwall, J., Freitas, A., Mattelaer, O.

Understand

The matrix element method (MEM) 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 MEM, 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.
