CERN’s LHC to look for a link between Higgs Boson and Dark Matter

By  | 

Scientists have been trying to look for the Dark Matter since decades and it seems that the CERN’s Large Hadron Collider could possibly find the answer or point physicists in the right direction – at least that’s what Christoffer Petersson, a research scientist at Chalmers University of Technology believes.

Petersson and his two research colleagues have proposed a new particle model based on what is known as supersymmetry wherein they say that the Higgs boson might be responsible for the birth of dark matter particles.

The new 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 wherein 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.

The researchers’ theory have met with a response at CERN and two independent experimental stations – Atlas and CMS – at the LHC will be looking for the very properties of the Higgs particle that Petersson’s 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 that two independent experiments are going to do it,” says Christoffer Petersson.

CERN’s previous experiments were not able to either confirm or reject Petersson’s theory owing to lack of required data; however, Zeynap Demiragli at the CMS experiment at CERN said that they are “already in full swing with new analyses in which we are testing his model in other ways and with more data.”

“We congratulate Christoffer Petersson for having done an important job,” added Petersson.

“If the model is found to fit, it would completely change our understanding of the fundamental building blocks of nature. If not, just the fact that they are willing to test my model at CERN is great,” he says.
