However, Ben Kilminster July 26th talk in Paris (ICHEP 2010) revealed that the combined Tevatron datasets contain 5 tantalizing events with an apparent light, 113-115 GeV, Higgs boson. That would softly confirm the rumor including my detailed information about the mass...
Official status so far:
Tevatron HTTP 404 error: Higgs not found
... and 115 GeV is the most likely mass ...

Your humble correspondent has claimed that the Higgs exists and is light - below 130 GeV or so - for years. Well, precision fits and SUSY, and all that. So the question about its discovery is not really "whether" but "when".
See also: What a light Higgs would mean for particle physics (click)Tommaso Dorigo brings us a rumor that the answer could be "now" and that a Fermilab collaboration - either the D0 Higgs Group or the CDF Higgs Group - is going to publish a 3-sigma evidence (99.7% confidence level) for a light Higgs particle, getting one step closer to confirming what your humble correpondent has said about the next discoveries in particle physics:
Rumors about a light Higgs (Dorigo)One must be careful about rumors, especially if they come from as shaky places as Tommaso Dorigo's blog. But even though there's a 99.7% probability that Dorigo's rumors are wrong, you still have a reasonable chance that the Tevatron has actually seen it. :-)

I would actually not reproduce the rumor if I thought it was less likely than 50:50 - that's the reason why I avoided similar bogus rumors in 2007 etc. But 50% is my guess for this particular new rumor.
Moreover, I think that if the rumor is true, the Higgs was spotted right at those 115 GeV; see The 115 GeV Higgs Odyssey and What if the Higgs Boson Weighs 115 GeV? for two stories about the scenario.
In November 2009, there was a known 2-sigma excess over there. When combined with the 1.7-sigma signal from the LEP2 death bad, this gave you (via Pythagorean addition) a 2.6-sigma signal already half a year ago. That translates to the 99% confidence level.
Even this rough calculation - and a similar one for the 1.7-sigma LEP2 signal - is enough for me to argue that it was a mistake that the LEP2 collider wasn't given a year or two of extra life. Although 1.7 sigma is just 91%, it's just way too much above 50% to be neglected in policy decisions that wouldn't cost much.
Given the signal, the "probability of a discovery per invested dollar" would be much higher for this extra year or two. Too bad that the responsible people don't think about these economic matters quantitatively.
A joke as a bonus
A Higgs boson walks into a church. The priest says: "We don’t allow Bosons in church." Boson: "How can you have mass without me?
