PD, I take 'rest mass' to mean internal motions (rotations) as opposed
to external motion, hence the so-called rest mass has a meaning
similar to the self-field energy which is the energy of a particle
that has internal structure, and whose constituent parts have kinetic
and potential energies, and in addition, they have self-field energies
of their own, plus we have a binding energy that keeps the sub-
particles in the structure. In other words you see a fractal-type mass
or self-field energy emerging.
This may very well be. Now, given the rest mass of the electron of 511
keV, you should be able to estimate the coupling strength of the
binding interaction and the energy scale at which the compositeness of
the particle will be seen in scattering experiments. Would you please
do that?
First are you saying "what is the binding energy of the photon?" and
what energy should be used in scattering experiments to be able to
"split the photon"?
I wasn't talking about the photon. I was talking about the electron as
an example of something with a nonzero rest mass.
Well I think we should be able to see spectrographic changes in photon-
photon collisions WITHOUT splitting the photon. These changes
(without thinking about the maths too long) should be linked to the
external and internal velocities before and after. Given the well-
known speed of light, we should just get a couple of scattering angles
and two BEFORE colous and two AFTER colours.
This is not evident in electron-electron scattering so far. At what
energies do you expect to see "spectrographic changes" in electron-
electron scattering, and why? I'd like a calculation please.
PD
and i'd like some experiments!! wanna swap details??

Look for quark & lepton compositeness searches. References to journal
articles are also listed if you want more details. There are many.
Your turn. I'd like to see a calculation of the scale at which you
expect to see compositeness.

Ok, but give me some time to come up to speed on this I'm reading the
pdf; I'll try to see how this ties in with SFT. Have a look at this
link btw about photon-photon scatterinbg plans for the future. It
would be good to know, based on a two-particle model of the photon
what would be expected. As I said, I would imagine that the two
photons would have a before and after energy (frequency-I mistakenly
called this 'colour' previously) which would be able to tell us
something about the sub-particles.
