Z' boson
Many of the new particle physics theories predict the existence of new heavy particles.
One of these particles you may already have heard about is the Higgs particle, which is needed in order to describe a mechanism that gives mass to all particles of the Standard Model. This particle is not yet found, only predicted by theory.
Another not yet found particle is the so-called Z' boson. This particle is a heavy partner of the Z boson and is also predicted by many theories beyond the Standard Model. This particle is a heavy partner of the Z boson and is also predicted by some theories beyond the Standard Model that require the introduction of a new weak force. In most realizations the decay and production of the Z' boson will be very similar to the decay and production of the ordinary Z boson, which we have already introduced on the previous pages. This means that we can use exactly the same techniques as you have already learned in order to look for the Z' boson! We can draw the Feynman diagrams for some Z' decays (so you can compare with the ones for Z).
Do you see any similarities to the Z decays?
