Among the subjects being treated by RQED theory, this report is devoted to the mass-radius relation obtained for the Z boson, and to that associated with a model of the Higgs-like boson.
A Z boson is first considered, having zero net electric charge, spin h/2[pi], a rest mass of 91 GeV, and an effective radius of about [10.
to the very existence of the Z boson as a carrier of the weak force, later demonstrated by the production of Z's in high energy collisions at the European Center for Nuclear Research (CERN).
As an example, Turner points out the accepted theoretical claim that elementary particles known as the W boson and the Z boson had no mass when the universe first exploded into being.
The missing energy suggests, as expected, that a Z boson was created along with the presumed Higgs boson and then decayed into a pair of neutrinos, which LEP's detectors can't pick up.
That theory predicted a new weakforce particle, called the Z boson, which physicists discovered in 1983.
A Z' particle, related to the Z boson but about 10 times as heavy, would carry the force.
The Z boson, which occupies a strategically central position in the standard model, serves as a particularly valuable probe of the theory.
The results indicate that the top quark is probably heavier than the Z boson, which has a mass expressed in energy units of 91 giga-electron-volts (GeV), or nearly 100 times the proton's mass.
If that is not exciting, 2 Photons naturally combined or connected at one of their recessive ends [-YY+] to form Electrons and Neutrinos and the extra Photon [Y-, Y+, Y+-] forms the W+- and Z Bosons.
Detectors at the LHC recorded products of various Higgs decay paths, including one (shown) creating Z bosons that produce four leptons (such as an electron, positron, muon and antimuon) and another path that ends up producing two photons.
These are heavier versions of the W and Z bosons, which are responsible for weak interactions.
