![]() Dark matter, which emits no light and cannot be directly observed, is thought to make up about 80% of all matter in the known universe, but scientists do not yet know exactly what it is. The Standard Model explains a lot of things about our physical universe, but it doesn't include gravity or dark matter, Beacham said. "With vast amounts of data expected from the High-Luminosity LHC programme, studying rare Higgs boson decays will become the new norm," according to a statement from ATLAS.īy studying rare decays like this, researchers can explore the possibility of new physics that stretches beyond the Standard Model. The data used for this study was collected during Run 2, the second running period for the collider that began in 2015 and ended in 2018. So far, experiments at the LHC have focused on testing the Higgs.

However, he added, the team likely won't be able to directly observe the rare decay until they upgrade the facilities for the upcoming High-Luminosity LHC program (which will come following the LHC Run 3. The Higgs boson, a fundamental scalar boson with mass 125 GeV, was discovered at the Large Hadron Collider (LHC) at CERN in 2012. Example one is you could have two gluons, infuse, give you Higgs Boson and the Higgs to decay into bottom quarks. While scientists have predicted that this type of decay should exist with the Higgs boson, this new detection is "the first hint of evidence of this very rare decay mode of the Higgs boson," Beacham said. Scientists can spot and study these particles when they're stopped or "absorbed" by the tool. The discovery of this, in 2012, using the then recently opened lhc, was a triumph of scientific prediction, the particle having been described theoretically by the eponymous Peter Higgs in 1964. In fact, the search for the Higgs particle (s) is some of the most exciting research happening, because it could lead to completely new discoveries in particle physics. The LHC's calorimeter is a tool that stops particles coming from a particle collision. The simplest theories predict only one boson, but others say there might be several. The Higgs boson is responsible for the mass of objects. The two leptons "hit our calorimeter really close to each other," Beacham added. ![]() ![]() In a new study, researchers working with the Large Hadron Collider found the first evidence for a rare Higgs boson decay. ![]()
