Scientists say they may have found 'God particle'

Scientists said Wednesday that they had discovered a new particle whose characteristics match those of the Higgs boson, the most sought-after particle in physics.

(CNN) -- Scientists said Wednesday that they had discovered a new particle whose characteristics match those of the Higgs boson, the most sought-after particle in physics, which could help unlock some of the universe's deepest secrets.

"We have reached a milestone in our understanding of nature," said Rolf Heuer, the director general of the European Organization for Nuclear Research, which has been carrying out experiments in search of the Higgs boson at the Large Hadron Collider (LHC), the world's largest particle accelerator.

"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," said Heuer.

Announcements by scientists about their analysis of data generated by trillions of particle collisions in the LHC drew avid applause at an eagerly awaited seminar in Geneva, Switzerland, on Wednesday.

The Swiss presentation comes after researchers in Illinois said earlier this week scientists that they had crept closer to proving that the particle exists but had been unable to reach a definitive conclusion.

Finding the Higgs boson would help explain the origin of mass, one of the open questions in physicists' current understanding of the way the universe works.

The particle has been so difficult to pin down that the physicist Leon Lederman reportedly wanted to call his book "The Goddamn Particle." But he truncated that epithet to "The God Particle," which may have helped elevate the particle's allure in popular culture.

Experts say finding the elusive particle would rank as one of the top scientific achievements of the past 50 years.

The Higgs boson is part of a theory first proposed by physicist Peter Higgs and others in the 1960s to explain how particles obtain mass.

The theory proposes that a so-called Higgs energy field exists everywhere in the universe. As particles zoom around in this field, they interact with and attract Higgs bosons, which cluster around the particles in varying numbers.

Imagine the universe like a party. Relatively unknown guests at the party can pass quickly through the room unnoticed; more popular guests will attract groups of people (the Higgs bosons) who will then slow their movement through the room.

The speed of particles moving through the Higgs field works much in the same way. Certain particles will attract larger clusters of Higgs bosons - and the more Higgs bosons a particle attracts, the greater its mass will be.
