Hi Greg,

We arrived at Fermilab and are at the hadron collider school. We have run the background for WZ, ZZ, WW, Wgamma. In the ued page http://d0server.hep.ift.unesp.br/~mercadan/ued/ued.htm we quote this background for lepton number. We have looked at some distribution but did not have the time to put in the page. We also have simulated several cuts (Et missing, njets, pt jet and sum of pt jets) and find out the best set of cuts to enhance the signal over sqrt(bg). This turns out to be hard ET sum and Et of one jets (Et missing did not help much).

We did not simulate non physics bg and one of the major bg might be W+jet with misid of the jet as a lepton.However I think this simulation should be done with
the full DZero machinary.

I think we might be at the point to prepare something to present at the NP group after the school. What do you think?

Best,

Pedro and Sérgio.
