Electron positron to w bosons
WebA few of the weak interactions make sense. An electron and a positron can annihilate to form a Z boson. Similarly, any standard model fermion and its antiparticle can annihilate to form a Z. An electron and an electron anti-neutrino can annihilate to form a W. Similarly, and lepton and the appropriate anti-neutrino can annihilate to form a W. WebThe bosons were then studied in more detail at CERN and at Fermi National Accelerator Laboratory in the US. In 1989, first physics results from the Large Electron-Positron …

The boson serves as an "interaction propagator" particle. Namely it is short lived and serves as the "carrier" of the weak force that governs the beta decay. Similar cases are in the strong interactions where qluons play this role or in electromagnetism, where the electromagetic force id mediated by photons. little brown bugs on couchW bosons had already been named, and the Z bosons were named for having zero electric charge. The two W bosons are verified mediators of neutrino absorption and emission. During these processes, the W ± boson charge induces electron or positron emission or absorption, thus causing nuclear transmutation.
