Abstract: (arXiv)

We present a study of effects of QCD radiation in the production of heavy colored states, employing inclusive multi-jet samples obtained by matching matrix elements and parton showers. We discuss several examples showing that matched samples are in general not only more accurate than a parton shower alone, but also often indispensable to make reliable predictions of beyond the Standard Model signals.
