A question researchers at the LHC are trying to answer is whether the properties of the Higgs boson are as predicted by the standard model. One way to do this is to look for extremely rare decays of the Higgs boson, as physicists in the CMS…

The Higgs boson is an extremely rare particle. At the Large Hadron Collider (LHC), where bunches of protons collide at more than 99.9999% of the speed of light up to forty million times per second, a Higgs is produced around once per second. The…
