We discuss the subject of matching the NLO QCD corrections to the parton shower for processes mediated by coloured resonances. In order to perform precise realistic simulations of the production of resonances their decay must be included. In current frameworks for NLO+PS simulations, however, problems arise when generating the radiation from the decay of the resonance, especially for narrow resonances. We outline steps towards a future consistent prescription for a framework for matching of NLO calculations involving intermediate resonances decaying into coloured particles with parton showers that fully accounts for finite width and interference effects.
