Beautiful Higgs decays

The discovery of the Higgs boson in 2012 explained something no less foundational than how subatomic particles gain mass. The particle’s discovery marked the beginning of a comprehensive effort to measure its properties. In June 2018, the CMS collaboration reported observing the Higgs boson produced in association with a pair of top quarks. This represented the first direct measurement of the Higgs boson coupling to quarks, a building block of matter. Now the CMS collaboration announces another major observation: The Higgs boson decays into bottom quarks, also known as the beauty quarks.
