Final Analysis Suggests Tevatron Saw Hint of the Higgs Boson 184
ananyo writes with exciting news from the world of particle physics: "A hint of the Higgs boson, the missing piece in the standard model of particle physics, has been found in data collected by the Tevatron, the now-shuttered U.S. particle collider at Fermilab in Batavia, Illinois. While not statistically significant enough in themselves to count as a 'discovery', the indications announced on 7 March at the Moriond conference in La Thuile, Italy, are consistent with 2011 reports of a possible standard model Higgs particle with a mass of around 125 GeV from experiments at the Large Hadron Collider at CERN near Geneva, Switzerland. The data is more direct evidence of the Higgs than the constraints on its mass offered by the precise W boson mass measurement reported on Monday. On a sad note, the find vindicates Tevatron scientists who campaigned unsuccessfully to extend the collider's run. The request was turned down by the Department of Energy but this last hurrah suggests that Tevatron might indeed have found the Higgs ahead of CERN's Large Hadron Collider if they'd secured the funding required. The Tevatron is currently being raided for parts."

Last years LHC proposed energy "bump" was only five contending events out of several trillion studied.
It's more than 5. For the ATLAS detector by itself, as of Dec 2011 [quantumdiaries.org] they had 89,760 probable Higgs events. (Whether or not they 'actually are' the Higgs remains to be seen of course.)
Your overall point about the low frequency of events is correct, though. Those 89k events are from 380 trillion proton-proton collisions, which translates to an efficiency of 2.4×10^(-10).

PS... NASA still has operating SR-71's, so we technically still have a plane capable of traveling at Mach 3.35. And, God only knows what the slow, Government-teat-sucking, mouth-breathing engineers have been able to cook up in the past 50 years. Maybe they have us up to Mach 4 now.
No they don't. They haven't since 1999...

Is finding proof of the Higgs Boson really the "most difference" that the Tevatron will have made during its long life?
No, it found the Top quark too, and that was really straining its capabilities, which is why the LHC was built (after the abandonment of the SSC).
