Today, scientists at CERN, the European Organization for Nuclear Research, have announced that, for the first time, they have observed the Higgs boson transforming into elementary particles known as bottom quarks as it decays. Physicists have predicted this to be the most common way in which most Higgs bosons should decay, but until now, it has been extremely difficult to pick out the decay’s subtle signals. The discovery is a significant step towards understanding how the Higgs boson gives mass to all the fundamental particles in the universe.
