Fermilab experiments close in on favored Higgs mass range (interactions.org)According to some high-precision techniques based both on D0 and CDF data - techniques that are not quite carefully described in the press release but the precise W-boson and top quark mass are the key - the Higgs mass is most likely to be between 114 and 137 GeV.

It is not clear from the press release how much new evidence that this interval is the right one they have actually found.
They say that they have analyzed 2/3 of the data that will be available by September 30th when the Tevatron shuts down. It means that the dataset will jump by 50% relatively to what we have now. There will be two separate (D0 and CDF) Tevatron talks about the Higgs tomorrow in the morning.
However, the full combined analysis by D0 and CDF will be presented on Wednesday July 27th at 3:00 p.m. French Summer Time, the last day of the EPS-HEP2011 conference. At 3:30 p.m., a similar plenary talk will consolidate all the LHC data on the Higgs which may tell us something even more accurate or striking than the 114-137 GeV interval. Only tea and outlooks from continents and from theory :-) will be awaiting the participants of the conference - and the excited scientific public observing the events through TRF and a few other means - afterwords.

Don Garbutt: The Higgs Field
The results in Grenoble seem to indicate a complete validity of the Standard Model. Still, the preferred value of the Higgs mass suggests that the Standard Model breaks down at relatively low energies so it can't be the whole story.
If supersymmetry is relevant, the superpartner masses probably exceed 1 TeV in most cases. Still, there's nothing wrong with it. I find the new inflow of robust and cold experimental results extremely refreshing. Pretty much all models that wanted to see new signals "behind the corners" have already been exterminated. This includes well-motivated models as well as the unmotivated ones.
You could say that I would be equally or more happy if the colliders were producing totally new and unexpected results. And you're right. I am happy while learning the truth about Nature whatever it is.
Still, the identity of the Higgs sector remains unknown and it may be the only unknown part of physics below 1 TeV. We could learn something tomorrow - on Friday - when new dozens of papers are likely to be released and they will be more relevant for the Higgs enigma than the papers released today.
