- Researchers at CERN have found evidence that confirm that Higgs boson particle decays into fermions as predicted by the Standard Model.
- The researchers achieved this by colliding protons in a 6-metre-diameter solenoid and using specialised detectors to find out which particles were produced in the resulting collisions.
- This serves as strong evidence towards establishing that the particle discovered in 2012 at CERN by researchers at ATLAS and Compact Muon Solenoid (CMS) is indeed the Higgs boson. It has a mass region of 125 to 126 gigaelectronvolts (GeV).
- The hunt was for particles known as tau leptons, which have a mass of around 1.7 GeV, making them around 3,500 times heavier than electron.
- Still much more work was needed to confirm, and researchers are now looking at confirming whether many different Higgs particles exist, as predicted by various extensions of the Standard Model.
