suggestion for CDF/D0 discrepancy

I think CDF and Dzero need to check their MC for exactness eg  the list of decay modes that were studied in MC in Dzero and in CDF need to be same atleast the ones that were reconstructed.. is it possible that Dzero missed a mode or a particular branching of that mode. Very likely. suppose one intermittent resonance is missing in case of one mode (or more) from the topography, at the generator or reconstructed level then this  could be the most likely case. The topography of all modes of both analysis needs to be matched…(and the modes that were reconstructed in the data). This list of modes needs to be same…and their topography at the generator and reconstruction need to be exctly same for both analysis…
