From Live Science, June 4, 2018: The Higgs boson appeared again at the world’s largest atom smasher — this time, alongside a top quark and an antitop quark, the heaviest known fundamental particles.
From NOVA NEXT, June 4, 2018: The CMS and ATLAS collaborations report a substantial new advance in the understanding of the Higgs boson, the particle that is responsible for giving mass to fundamental subatomic particles.
From CNN, June 4, 2018: Scientists from the CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed the most massive known fundamental subatomic particle directly interacting with an energy field that gives mass to the building blocks of the universe.
From The New York Times, May 28, 2018: At CERN in Switzerland and Fermilab in Illinois, there is always a sense of discovery — about the past, present and future.
Earlier today the CMS paper titled “Observation of ttH Production” was accepted for publication by Physical Review Letters. In this article, the CMS collaboration presented the first observation of the coupling between the Higgs boson and the top quark. The strength of this coupling as measured by CMS is consistent with the Standard Model expectation. This observation connects for the first time directly the two heaviest elementary particles of the Standard Model: the top quark, which was discovered in 1995… More »
