Once the event jets have been reconstructed, the collection of primary hypotheses are then restricted to those events with a $p_T > 20$ GeV as well as requiring at least 2 jets to have passed the criteria above. A minimum combined invariant mass of 20 GeV as well as a minimum difference in mass between the two pairings of 100 GeV is set to prevent events containing fakes and photons to be considered in the analysis.   In order to prevent events originating from a process similar to Drell-Yan, a z-veto was added to the selection criteria by restricting events to having a combined invariant momentum that does not fall within 15 GeV of the mass of the Z-boson (approx 91 GeV).
