Higgs boson may be a mirage, scientists hint
By Robert Evans
GENEVA (Reuters) - Scientists chasing a particle they believe may have played a vital role in creation of the universe indicated Monday they were coming to accept it might not exist after all.
But they stressed that if the so-called Higgs boson turns out to have been a mirage, the way would be open for advances into territory dubbed "new physics" to try to answer one of the great mysteries of the cosmos.
The CERN research centre, whose giant Large Hadron Collider (LHC) has been the focus of the search, said it had reported to a conference in Mumbai that possible signs of the Higgs noted last month were now seen as less significant.
A number of scientists from the centre went on to make comments that raised the possibility that the mystery particle might not exist.
"Whatever the final verdict on Higgs, we are now living in very exciting times for all involved in the quest for new physics," Guido Tonelli, from one of the two LHC detectors chasing the Higgs, said as the new observations were announced.
CERN's statement said new results, which updated findings that caused excitement at another scientific gathering in Grenoble last month, "show that the elusive Higgs particle, if it exists, is running out of places to hide."
The centre's research director Sergio Bertolucci told the conference, at the Indian city's Tata Institute of Fundamental Research, that if the Higgs did not exist "its absence will point the way to new physics." Continued...
