The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator. It was built by the European Organization for Nuclear Research (CERN) from 1998 to 2008, with the aim of allowing physicists to test the predictions of different theories of particle physics and high-energy physics, and particularly for the existence of the hypothesized Higgs boson and of the large family of new particles predicted by supersymmetry.

The newcomer is called Chi-b(3P), which was uncovered in the debris from colliding protons, according to research published in the open-access online journal arXiv.Like the elusive Higgs and the photon, it is a boson, meaning it is a particle that carries force.But while the Higgs is not believed to be made of smaller particles, the Chi-b(3) comprises two relatively heavy particles, the beauty quark and its antiquark.They are bonded by the so-called "strong" force which also causes the atomic nucleus to stick together.The Chi-b(3P) is a heavier version of a particle that was first observed around 25 years ago."The Chi-b(3P) is a particle that was predicted by many theorists, but was not observed at previous experiments," said James Walder, a British physicist quoted by the Univer...The world's largest particle accelerator, the Large Hadron Collider , has set a new world record for colliding two beams of more particles together than ever before....
