Higgs boson: Landmark announcement clears key hurdle

Two laboratories working at the European Organisation for Nuclear Research (CERN) had jointly announced on July 4 they had detected a new in experiments at the near Geneva.

The discovery has been hailed as one of the biggest scientific achievements ever.

The teams, from labs called Atlas and the (CMS), on Monday each published their findings in the European journal Physics Letters B.

They are available at www.sciencedirect.com/science/ … ii/S037026931200857X and www.sciencedirect.com/science/ … ii/S0370269312008581 .

Although CERN's announcement was never doubted, it still had to be vetted by peers and then published in an established journal to meet benchmarks of accuracy and openness.

Further work is being carried out to confirm whether the new particle is the famous , whose existence was theorised back in 1964 to explain why obtain mass.

Without the Higgs, atoms could not form, which means the physical Universe would not exist, say scientists.

"The discovery reported in these papers is a momentous step forward in fundamental knowledge," said Atlas spokeswoman Fabiola Gianotti.

"It is the culmination of more than 20 years of effort of the worldwide high-energy physics community to build and operate instruments of unprecedented technology, complexity and performance."

More than 5,000 researchers worldwide took part in the long quest, and both papers are dedicated to the memory of colleagues who had died.

Physics Letters B was where British physicist Peter Higgs first published a letter, "Broken symmetries, and gauge fields," that sparked the hunt for the boson.

His name is attached to the particle, but two other groups of theoreticians can also claim to have made major contributions.
