With the recent combination of results and update in new high data set experiments the Tevatron has extended the exclusion of the possible mass range to the Standard Model Higgs Boson to an even larger range than before. If you take this result and couple it with other measurements this make an excellent case for one of three scenarios as I understand it (Warning: I am not working directly on a Higgs search at CDF so this is just to the best of my understanding as a rising physicists)
1) The Higgs boson is a low mass boson (between 120 - 160 GeV) and and thus has a very difficult signal to see (and will be a nightmare to detect at the Large Hadron Collider because of the increase in background production at the higher energy) and will require more data to see at the Tevatron in addition to more sophisticated analysis techniques.
2) The Higgs boson is a non-Standard Model scenario and thus has some weird decay/signal mechanism that either is overlooked or hasn't been produced yet....(I don't know what this could be but a SUSY like Higgs doublet would be one such weird scenario)
3) We've got this all wrong and we need to go back to the drawing board when it comes to our understanding of nature...(not all that likely, but I think the most interesting of the possibilities)
Stay tuned as the results update
