Now we know, the Higgs boson did not show up at Tevatron. Yet.
But we also know that, if it exists, we would not find it in the 158-175 GeV mass range. The saga of the Tevatron Higgs talks finally came to an end, certainly matching the expectation, at least for what concerns the show part. Well, as for the scientific part, after all the preliminary steps of the last days nobody was really any hint of signal anymore. We mortals might not be able to make fancy statistical combinations by eye, but it was still not too complicated to anticipate that, since there was no excess in any channel or single detector combination, we should not have expected any dramatic announcement.
I found Ben's talk really excellent: the slides (that, by the way, were kept secret until the very last moment) were very well prepared, and Ben proved to be an excellent presenter. In a sense he was even rather humble, especially if you think about the fuss about a possible signal before the conference (at slide 46: "I'm sorry, this 2 sigma excess is the closest we have to a discovery"!).
and casually commented: "People keeps on asking how would the exclusion plot look like if there existed a Higgs boson. We did the exercise of injecting a 115 GeV SM Higgs boson signal in several channels, and that's what we got". And, guess what, the results is that the exclusion curve jumps up like it had a 1 sigma fluctuation on a rather large mass range. Now, doesn't this jump remind you of any feature we saw in another curve? There a region where the unspeakable dreams and hopes of many live, between a green and a yellow band.
