Physicists have spotted the Higgs boson performing a new trick, but one that brings us no closer to understanding the workings of fundamental particles.

The Higgs boson, discovered at the CERN particle physics laboratory near Geneva, Switzerland, in , is the particle that gives all other fundamental particles mass, according to the standard model of particle physics. However, despite the work of thousands of researchers around the world, nobody has been able to figure out exactly how it does that or why some particles are more massive than others. Electromagnetism is carried by photons and involves the interaction of electric fields and magnetic fields.

The strong force, which is carried by gluons, binds together atomic nuclei to make them stable. The weak force, carried by W and Z bosons, causes nuclear reactions that have powered our Sun and other stars for billions of years.

The fourth fundamental force is gravity, which is not adequately explained by the Standard Model. Despite its success at explaining the universe, the Standard Model does have limits. For example, the Higgs boson gives mass to quarks, charged leptons like electrons , and the W and Z bosons. How was its existence proved at the LHC? This video explains the basics of the Higgs boson and its associated field in 4 minutes with infographics.

Real CMS proton-proton collision events in which 4 high energy muons red lines are observed. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes. Image: CERN. The Higgs boson Elementary particles gain their mass from a fundamental field associated with the Higgs boson. The Brout-Englert-Higgs mechanism In the s, physicists realised that there are very close ties between two of the four fundamental forces — the weak force and the electromagnetic force.

The top event in the CMS experiment shows a decay into two photons dashed yellow lines and green towers.
