CDF has recently shown a 4+ sigma excess in dijet mass around Mjj = 144 GeV in their search for WW, one W decaying semi-leptonically and one decaying hadronically. Careful examination has shown this is very unlikely to be the Higgs, and if the results are born out, perhaps some new particle. DZERO has recently completed its own analysis of their data, searching in the same channel: nothing is seen. I will describe a bit of the history, the DZERO analysis, and some comparisons of the two experiment's analyses.
