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.
Physicists describe the smallest constituents of nature – elementary particles and forces acting between them using a set of theories known as “the Standard Model”. This model was developed in the 1970s and has been very successful, particularly in predicting the existence of undiscovered particles…
…This model contains more elementary particles than the Standard Model, including dark matter particles. In addition, the model gives the Higgs particle different properties than the Standard Model predicts. The model proposes that the Higgs particle can distintegrate into a photon (a particle of light) and particles of dark matter. However, these properties are quite difficult to discover – you have to look for them specifically to have a chance of finding them.
But Christoffer Petersson is fortunate – his model has met with a response at CERN. Two independent experimental stations – Atlas and CMS – at the Large Hadron Collider are now looking for the very properties of the Higgs particle his model predicts. If the properties are there, it is a clear indication that the model fits.
“It’s a dream for a theorist in particle physics. LHC is the only place where the model can be tested. It’s even nicer. Edited from Higgs particle can disintegrate into particles of dark matter, according to new model.
