Scientists have announced at a seminar held at CERN, the European Organization for Nuclear Research, that they have found the new subatomic particle that appears to be the boson imagined. Experiments from both the ATLAS and CMS observed the new particle in the mass region from around 125-126 GeV at the level of 5 sigma.
Fabiola Gianotti, ATLAS experiment spokesperson, said that these results have been obtained by the combined efforts of a large number of people “but a little more time is needed to prepare these results for publication.” According to Joe Incandela, CMS experiment spokesperson, the new particle is “the heaviest boson ever found”.
“It’s hard not to get excited by these results,” said CERN Research Director Sergio Bertolucci. “ We stated last year that in 2012 we would either find a new Higgs-like particle or exclude the existence of the Standard Model Higgs. With all the necessary caution, it looks to me that we are at a branching point: the observation of this new particle indicates the path for the future towards a more detailed understanding of what we’re seeing in the data.”
According to CERN press release, today’s results are preliminary as they are based on data obtained in 2011 and 2012 while the data of 2012 is still under analysis. However, more data obtained by the experiments of LHC later this year will give a good explanation to the today’s reported results.
The results reported today would be published at the end of this month.
“We have reached a milestone in our understanding of nature,” said CERN Director General Rolf Heuer. “The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle’s properties, and is likely to shed light on other mysteries of our universe.”
