Higgs particle can disintegrate into particles of dark matter, according to new model. The 'Standard Model' of particle physics successfully describes the smallest constituents of matter. But the model has its limitations – it does not explain the dark matter of the universe. Christoffer Petersson, a research scientist at Chalmers University of Technology, has found a solution. His theories are now being tested at the particle physics laboratory CERN.
Lead ion collision at the Large Hadron Collider. This is the world's highest-energy particle accelerator. Up until now, they were colliding protons. Using lead ions, they created temperatures a million times hotter than at the centre of the Sun.
