Dark matter has long remained one of the best unraveled mysteries of the universe. While its presence can be deduced from the gravitational pull it applies on visible matter, the fact that it doesn’t absorb or retain any radiation makes it very difficult to recognize.
When CERN’s Large Hadron Collider (LHC) recommences operation in May of this year, researchers will try to test another model of particle physics – one that tries to clarify the starting point of the mysterious dark matter that constitutes more than 84 percent of the total matter in the universe.
The new model set forward by a team headed by Christoffer Petersson, a theoretical particle physicist from Chalmers University of Technology in Sweden, proposes that the Higgs boson, found by the LHC in 2012, may be in charge of the conception of dark matter particles. As indicated by this model, if supersymmetry is genuine, the Higgs molecule can deteriorate into a photon – a light conveying particle – and a dark matter particle.
Supersymmetry predicts that there are more huge “super patners” for each known molecule, and is an expansion of the Standard Model of particle physics, which administers our comprehension of the quantum world. The Higgs boson, which is in charge of granting mass to all different particles, was the last missing piece that finished the Standard Model. On the other hand, even the finished variant of this hypothesis neglects to join gravity and clarify the source and dominance of dark matter in the universe.
The model set forward by Petersson and his group would be tried by two independent experimental stations – Atlas and CMS – at the LHC, which will restart at much higher energies in March, following a gap of two years.
“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,” Petersson said, in a statement.
The hypothesis has found support among scientists at CERN, who, in the expressions of Tara Shears, a particle physics professor from the University of Liverpool, are looking to “break” the Standard Model.
“Instead of trying to test the truth of this theory, what we really want to do now is break it — to show where it stops reflecting reality. That’s the only way we’re going to make progress,” Shears told BBC. “We’re looking at something deeper and more exotic.”
It affirmed, Petersson’s model can possibly totally change our fundamental understanding of the universe and would be a vital venture to forming the widely inclusive Theory of Everything. “If not, just the fact that they are willing to test my model at CERN is great,” Petersson said.
