Needing a way out of this problem, several physicists proposed a mechanism to account for the broken symmetry. It also leads, without corrections, to nonsensical predictions – for example, interactions with probabilities greater than 100%. The fact that the W and Z boson are massive breaks the fundamental electroweak symmetry. The photon, carrier of the electromagnetic force, is found to follow that precept however, the W and Z bosons, carriers of the weak force, have a mass. The symmetry responsible for electroweak unification requires the force-carrying particles involved to have no mass. In particular, the Standard Model as originally conceived could not explain one basic observation: why most elementary particles have mass. But our understanding of Nature is incomplete. The Standard Model successfully describes all of the elementary particles we know and how they interact with one another. The theory of electroweak interactions and Quantum Chromodynamics (the theory of the strong force) form the basis of the Standard Model. These two forces can be described by a single theory: electricity, magnetism, light, and some types of radioactivity are all manifestations of a single underlying force called the electroweak force. A major breakthrough occurred five decades ago when physicists realized that there are very close ties between the weak and electromagnetic forces. From around the turn of the last century, physicists have tried to unify these forces under a single, overarching theory. Our Universe seems to be described by four fundamental forces: gravity, electromagnetism, the weak force (which regulates nuclear phenomena like fusion within stars), and the strong force (which keeps atomic nuclei together). It started about 50 years ago and was considered impossible for decades, which is one of the main reasons the LHC was built. The search for the Higgs boson is one of the most fascinating scientific adventures. This theory explains how fundamental particles acquire their mass. The Higgs boson is the fundamental particle predicted by the Brout-Englert-Higgs mechanism.
