Significant Progress at LHC!

In the seminar back at 12th of December held at CERN presented the current results of the search of Higgs boson. The great news was that some significant progress was made. Yet Higgs boson is still not found, let's check out what's  the latest progress update from CERN is all about.

The main conclusion of the seminar was that the most likely mass ranges of Higgs was discovered to be 116-130 GeV  and  115-127 GeV. What is even more amazing that huge hints of Higgs were detected in the latter mass region, yet it's still too weak to confirm the discovery of the particle.


Here's a qoute from the press release:

"We have restricted the most likely mass region for the Higgs boson to 116-130 GeV, and over the last few weeks we have started to see an intriguing excess of events in the mass range around 125 GeV," explained ATLAS experiment spokesperson Fabiola Gianotti."This excess may be due to a fluctuation, but it could also be something more interesting. We cannot conclude anything at this stage. We need more study and more data. Given the outstanding performance of the LHC this year, we will not need to wait long for enough data and can look forward to resolving this puzzle in 2012."
"We cannot exclude the presence of the Standard Model Higgs between 115 and 127 GeV because of a modest excess of events in this mass region that appears, quite consistently, in five independent channels," explained CMS experiment Spokesperson, Guido Tonelli. "The excess is most compatible with a Standard Model Higgs in the vicinity of 124 GeV and below but the statistical significance is not large enough to say anything conclusive. As of today what we see is consistent either with a background fluctuation or with the presence of the boson. Refined analyses and additional data delivered in 2012 by this magnificent machine will definitely give an answer."
