11. During these processes, the W boson charge induces electron or positron emission or absorption, thus causing nuclear transmutation. 12. The W bosons can subsequently decay either into a quark and an antiquark or into a charged lepton and a neutrino. 13. In December 2016, ATLAS presented a measurement of the W boson mass, rearching the precision of analyses done at the Tevatron. 14. The Feynman diagram for beta decay of a neutron into a proton, electron, and electron antineutrino via an intermediate heavy W boson 15. As for the W and Z bosons, if I'm understanding the article correctly, the W bosons interact electromagnetically but the Z doesn't. 16. Beta decay is a consequence of the W boson and the creation of an electron / antineutrino or positron / neutrino pair. 17. Here is the coupling constant of the weak interaction, and is the mass of the W boson which mediates the decay in question. 18. This theory has made a number of predictions, including a prediction of the masses of the Z and W bosons before their discovery. 19. These are the parameters that are most easily produced and detected ( in the case of neutrinos, by weak interactions involving the W boson ). 20. Similarly, the are antiparticles of each other, but the fundamental W bosons are their own antiparticles in the same sense as the other gauge bosons.
