I have been writing a paper on my preon model #5 for the last month or more. Hopefully to go on vixra. No chance of arxiv as the paper is not mathematical nor do I now have an address on campus. I had almost finished the paper, dotting 'i's, crossing ts and cross-checking, when I found an error in the weak force treatment one week ago. Fortunately, I have recovered a preon structure using a new model, #6.

I should have spotted the error long ago, or been wise enough to have avoided the error in the first place. My error was to assume the following incorrect eigenstates for the up quark and the neutrino:

where () = (electric charge, spin, weak isospin)

LH up = (2/3, -0.5, -0.5)

LH ν = (0, -0.5, -0.5)

whereas they should be:

LH up (2/3, -0.5, +0.5)

LH ν (0, -0.5, +0.5)

But I have now corrected this. It required a fourth preon, preon D, with properties (-0.5, 0, +0.5) in order to be able to build the ν and up quark using only four preons to conform with the pattern for the first generation elementary particles.

There were two other structural effects: the higgs (0,0,-0.5) can now be built in two different ways: ABC'C' X6 as before but also as D'C X7 (where Xn is n neutral pairs of preon + antipreon).

Also, there must be two different forms of W- : (-1,-1,-1) and (-1,+1,-1). This is because to send an LH up (2/3, -0.5, 0.5) to a RH down (-1/3, 0.5,0) requires an addition of (-1, +1, -0.5) while to send a RH up (2/3,0.5, 0) to a LH down (-1/3, -0.5, -0.5) requires an addition of (-1,-1,-0.5). That requires the two forms of W-. And the extra 0.5 weak isospin that is needed comes from a 1/4 higgs which complies with many interactions in my preon model which require the 1/4 higgs or 1/2 higgs or higgs as a participant.

I have also introduced a new term which correlates exactly with electric charge: hypertone. The preons have hypercolour which aggregate to quark colour in a way that has no dependence of electric charge on quark colour. The red up and red down are both red yet have opposite electrical charge. But if the hypercolour of the preon is relabelled as white (=-1) for coloured preons and black (=1) for anticolour preons then blackness and whiteness represent tonal values for the preons. Aggregating the tonal values across preons in an elementary particle gives an exact match for electric charge in my model. I named the tonal value of the preon as 'hypertone' and because I am an amateur artist (see my wordpress website) this use of tonal values pleases me more than anything else that I have done in the preon model. It also give a connection between QCD and QED caused by aggregation and losing degrees of freedom in that aggregation process. An arxiv paper on preon models used 'hypercolour' for the colours on the preons, which is why I used hypertone rather than tone and I am now also using the term hypercolour for the preon 'colours'.
