### Can an elementary particle truly be destroyed?

In any process involving the creation and annihilation of particles there will be conserved quantities that must be the same before and after the process, and the most obvious of these is energy. For ...

### Does the Higgs field create time?

Not within the framework of known physics. The Higgs is described in quantum field theory, a theory in which space-time is a "pre-existing" notion, with fields being functions of space and ...

### The Dirac equation predicted the positron. Does the Dirac equation also suggest the existence of muons?

At the time when Dirac first published his famous equation, only electrons were known to physicists. That's why it was thought to describe electrons. The mass term in the Dirac equation is just the ...

### The Dirac equation predicted the positron. Does the Dirac equation also suggest the existence of muons?

It does not predict muons or tauons. They are still solutions but that doesn't mean it predicts them. What is special about the Dirac equation is that it predicts 2 pairs of solutions: anti-particles ...

### On neutral Kaon mixing

It is a terrible misconception to predicate flavor mixing (strangeness oscillations here) on CP violation. Flavor mixing was investigated (Gell-Mann―Pais, 1955, and the experiments probing it, 1957, ...

### On the quark composition of baryons

In OP's table the first 4 rows (=the isospin quadruplet) are the $\Delta$ particles, which sit inside a spin-$3/2$ $uds$ baryon decuplet. The 4th and 3rd last rows are the proton and neutron, ...

### What is the radius of the neutron?

You are plain unfair in your "without credible reference" for WP. Argue why you believe the text cited is not credible (!?). I don't agree with its number, but I suspect they argue in a ...

### Can we detect and measure color charge?

It is not helpful practice to talk about electric and color charges in the same breath, except to contrast them with extreme prejudice. Electric forces are macroscopic and so you may detect electric ...

### What would happen if you reduced the coupling of $SU(2)$ in the standard model to zero?

It is straightforward to see, even though your ultimate vision should be in trouble. I assume you mean decrease the coupling g of just SU(2), and leave the EM coupling e and the Higgs v.e.v. v alone, ...

### Is the Higgs field stronger in the presence of mass?

The Higgs field is a Lorentz scalar, which is unusual. It exists everywhere with the same value. If you rotate, it looks unchanged, and if you boost yourself to 99.9999% $c$, it looks the same. Very ...

### Can we synthesis pico materials or femto materials?

This is really a comment: I was wondering if it is possible to synthesis these materials involving just the particles. Elementary particles are what "synthesize" the atoms, within our ...
