Analysis 'strongly indicates' Higgs boson found, CERN scientists say
Researchers stop short of unequivocally claiming that the long-sought elementary particle Higgs boson has been discovered.

Analysis of the tracks of an elementary particle found in the Large Hadron Collider last year "strongly indicates" that it is the long-sought Higgs boson, the CERN physics research center said on Thursday.
But a statement on the latest findings from huge volumes of data gathered during three years of collisions in the LHC stopped short of claiming the boson, believed to be the particle that gives matter to mass, had been discovered for sure.
Measurement of the behavior of the particle, whose existence was first postulated in the early 1960s, and of its interaction with other particles "strongly indicates that it is the Higgs boson", CERN said.
The statement came after a presentation of the latest findings by CMS, one of two teams working on Higgs, at a physics conference in the Italian Alps, south of Geneva where CERN – the European Organization for Nuclear Research - is located.
"The preliminary results with the full set of 2012 data are magnificent, and to me it is clear that we are dealing with a Higgs boson, although we still have a long way to go to know what kind of Higgs boson it is," said CMS spokesman Joe Incandela.
The CERN statement said it still had to be established whether the boson is a simple Higgs, filling in the last hole in the 30-year-old Standard Model of how the universe works at the elementary particle level, or something more exotic.
