We study the matching of multijet matrix elements and shower evolution in the case of top production in hadronic collisions at the Tevatron and at the LHC. We present the results of the matching algorithm implemented in the ALPGEN Monte Carlo generator, and compare them with results obtained at the parton level, and with the predictions of the MC@NLO approach. We highlight the consistency of the matching algorithm when applied to these final states, and the excellent agreement obtained with MC… 

Hadronic top-quark pair-production with one jet and parton showering

Jet matching and subtraction methods for associated squark-gluino production

In hadron-hadron collisions, e. g. at the Large Hadron Collider (LHC) at CERN in Geneva, one of the most promising signatures for physics beyond the Standard Model is jets plus missing transverse
