Hard Diffraction has been subject of studies for more than 10 years and its event selection has been heavyly based on rapidity gaps because of the colorless nature of the pomeron but soft gluon emission tends to destroy the gaps lowering the efficiency to identify those events. We present here a first attempt to use techniques developed at DELPHI, one of the 4 experiments at LEP, to select diffractive events in Dzero experiment, at Tevatron. All results presented here are very preliminary.
