This is the tenth thread in the series on the ABC Preon Model. Links to earlier threads will appear in the comment below.
In the previous thread we took an initial look at the results from proton antiproton
. But another branch of high energy physics experimentation involves experiments done in electron positron colliders.
Above we see the process of an electron positron collision as modeled by the ABC preon model. An electron, composed of an A anti-preon and a B preon,
collides with a positron, which is an A preon and an anti-B preon. We've seen in the
how the production of a free A anti-A pair leads to what is known as the Z Signature in proton antiproton colliders, and here we
can see that the same production will take place in electron positron colliders.
The Z signature will result when the mass of the collision is such that the B and anti-B annihilate, leaving a free A anti-A pair. Once that happens,
a B anti-B pair and a neutrino pair can be produced from vacuum, leading to two leptons which is one signature for the Z particle. But in addition to
forming a lepton pair, it is also possible that C anti-C pairs can form from vacuum as well, and that will lead to various quark anti-quark
combinations. Hence, it can be noted that the ABC preon model nicely dovetails with the Standard Model. All of the various lepton and quark production
channels known to exist in the standard model can also be seen to occur through the ABC Preon Model for what are known as Z events. Of course this is
the idea behind all preon models. The idea is that a simpler precursor model underlying the quarks and leptons will reproduce known results by leading
to an understanding of the composition of what are now known as quarks and leptons.
So it is clear that A anti-A pairs can be easily seen to result from electron positron colliders, and we can see how that production is consistent
with known experiments. But note that it should also be possible to produce B anti-B pairs as well, through annihilation of the A anti-A portions of
the electron and positron. In that case, massive leptons will be produced through A anti-A and neutrino pair creation, and quark anti-quark pairs will
also be produced through C anti-C and neutrino pair production. This leads to a prediction for new physics from the ABC Preon Model. A signature that
has the same decay channels as the Z signature should also exist at 69.6 GeV in electron positron colliders. Note that it may not be as strong a
signal as the one at 91.2 GeV, but it should exist.
As a reminder of where the energies 69.6 GeV and 91.2 GeV come from, recall that the prior
showed us that the mass of the B is 34.8 GeV/c^2 and that the mass of the A is 45.6 GeV/c^2. A B anti-B formation will occur at twice the
mass of the B times c^2, or 69.6 GeV. An A anti-A formation will occur at twice the mass of the A times c^2, or 91.2 GeV.
And now let's return to a look at proton antiproton collisions. We saw in the prior
how the ABC preon model leads to an understanding of what are presently described as W events through the formation of an anti-A preon
and a B preon. We also saw how the model led to an understanding of what are presently described as Z events through the formation of an A anti-A
preon pair. But as was the case for the electron positron collisions, it should also be possible to form a B anti-B preon pair in proton antiproton
colliders. Hence, the same decay channels seen at the 91.2 GeV Z peak should also be seen at 69.6 GeV in proton antiproton colliders. Since there are
only half as many B particles as there are A particles in the proton, and half again as many anti-B particles as anti-A particles in the antiproton,
this will lead to only a quarter of the amount of production at the lower energy than there is at the high energy. Additionally, the cross section for
production may be smaller, as evidenced by the more tightly bound B particles in the down family of quarks. But the signal should exist at some level.
