At least two experiments at CERN’s large Hadron Collider (LHC) have produced results that suggest… no one is willing to say “prove” yet… that the Higgs boson exists, in the expected energy range. An energy of around 126 GeV has also been suggested. One problem in detecting the Higgs boson is that it is detectable only by its decay results, and if it exists, it has a large variety of ways in which it can decay.
Why is the Higgs boson important? Two reasons:
- it is the only particle predicted by the Standard Model of particle physics that has not yet been observed (or maybe it has!),
- it is the particle that gives other particles mass.
If they find it, things will get interesting. If they don’t find it, things will get even more interesting… a lot of physics will have to be reinvented.
