Peter Higgs is confident that the subatomic particle detected last July by scientists at the $10 billion Large Hadron collider (LHC) was the Higgs boson, which he had predicted more than half a century ago.

Peter Higgs had predicted the existence of the Higgs boson in 1964, but Switzerland-based LHC - a multinational effort of more than one hundred countries - could detect a similar subatomic particle only last year.

While scientists at CERN's LHC are yet to confirm whether the detected particle was the long-sought-after Higgs boson, Peter Higgs is sure that it was.

Speaking to reporters on Tuesday, Peter said, "I think it will turn out to be (the Higgs boson), but it's just a question of getting out the additional information."

Eighty-three-year-old Peter Higgs has already retired from active research, but the sudden detection of the particle by the LHC last year brought him back into limelight.

Belgium's renowned physicist Francois Englert, who had also theorized the subatomic particle, is also confident that the particle detected by the LHC was Higgs boson.

Before delivering a speech at the European Parliament in Brussels, Englert said that the results of the study were not yet confirmed but he was ready to bet that the detected particle was Higgs boson.
