Structure conservation (an extension of Energy-momentum-charge conservation) seems to imply that neutrinos should interact by the Strong Force. The neutrinos don't bind with the nuclei because they travel so fast.

Could this be true?

"Do Neutrinos Interact by the Strong Force?"
No.

Structure conservation (an extension of Energy-momentum-charge conservation) ...

I don't know if the word charge is appropriate for the neutrino. Because neutrinos are electrically neutral and are known to have negligible interaction with matter, since neutrinos can react with it only by the weak force during radioactive decay. Neutrinos are leptons, and leptons do not participate in the strong force.

If neutrinos interacted with the strong force, you'd expect them to interact with atomic nuclei far more readily than they actually do.

Then Color charge is not conserved by the Weak Interaction. Is this true?

[Kryptid]

The net color charge of any hadron is white. So when any hadron decays into any other hadron (whether by the weak force or any other interaction) color charge is conserved.

[evan_au]

In our universe, neutrinos only interact via the Weak Nuclear Force.

However, in the high-energy conditions shortly after the Big Bang, it is thought that our 4 separate forces would have been unified, so the behaviour of particles would have been quite different.

And of course, we really don't know in what sort of interactions that Dark Matter may participate.

Structure conservation

The conservation Law that ruled atomic physics in 1950s & 1960s was "CP Symmetry".
But in 1960s, hints were seen that some Weak interactions violated CP symmetry, for which a Nobel Prize was awarded in 1980.
Now the main theory is "CPT Symmetry".

My model predicts that neutrinos have colour charge, but they are colour neutral, so the Weak Force need not violate colour charge conservation.

[Kartazion]

My model predicts that neutrinos have colour charge ...

You mean neutrinos due to decay? Or do you mean quark neutrinos? Because quark neutrinos do not exist, and the charge color is specific to quarks and gluons only. This is chromodynamics.

[talanum1 (OP)]

Neutrinos from decay of pi+/-, or other mesons. My structure conservation requires neutrinos to have neutral colour.

Your stuff is frequently wrong.

Even if they are color neutral?

[Kryptid]

Even if they are color neutral?

Yes. Protons and neutrons are color neutral and they interact very well with the strong force.
