Searching for the Higgs Boson

Physicists have found a particle, consistent with the Higgs boson

When a Higgs boson is produced in a particle physics experiment, it will decay, almost instantly, to other particles.  Physicists search for the Higgs by looking through the data for the particular signature caused by the particles the Higgs boson decays into.

The key parameter physicists will measure once they have discovered the Higgs boson, usually denoted as mH.

Particle Physicists measure the mass of subatomic particles such as the Higgs boson in units denoted as GeV/c2.  1 GeV/c2 is equivalent to 1.79 x 10-27 kg, or roughly the mass of the proton. Here we present four historical searches for the Higgs boson.


  • What does the Higgs boson decay into?  
  • It decays into a pair of fundamental particles.  The fundamental particles we know we call leptons, quarks and gauge bosons.  Future measurements will tell us more about which particles the Higgs decays into, and how often.  ‚Äč
