LHC

From Live Science, June 4, 2018: Fermilab scientist Don Lincoln writes about two new results on how scientists found the Higgs boson popping up along with the heaviest particle ever discovered. The results could help us better understand one of the most fundamental problems in physics ­— why matter has mass.

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 »
