THE FOLLOWING REFERS TO THE PERMANENT ELECTRIC DIPOLE MOMENT


Fundamental particles like electrons and neutrons are predicted by the Standard Model (the current theory of all fundamental particles)
to have permanent electric dipole moments, but they are far too small for existing experiments to measure. Postulated new physics theories, however, predict much larger values of electric dipole moments, which could put them in reach of experiments. Over the next few years the measured limits will be improved by two to three orders of magnitude on the electron and neutron. There are also plans to measure electric dipole moments of atoms, molecules, and nuclei.

An electric dipole moment occurs when the negative charges in a particle are separated from positive charges. Such a separation
violates the combined symmetries of parity and charge conjugation (CP violation). CP violation means that there is difference in the way particles and antiparticles behave. In 1967, Andrei Sakharov pointed out that the only way to explain the fact that most of the universe consists of particles, not antiparticles, is to have particle interactions which do not conserve CP. Since then, a very small level of CP violation has been found in the decay of certain particles (kaons and B-mesons), but it is far too small to explain the asymmetry between matter and antimatter
in the universe. New sources of CP violation are being sought experimentally with high priority being given to experiments aimed at finding new sources of CP violation, for example in searches for electric dipole moments.

Which particle will be the first to be measured to have a non-zero dipole moment, and what will its value be?
What will be its source, the strong, electromagnetic, or weak force?

That would be a monopole which was first discovered in a cosmic-ray detector 25 miles above Sioux City, IA in the mid-70's with a value of +1. It's source was the electromagnetic force.

QL, I asked my friend who's getting a physics degree this fall the question and he told me that he is confused what you are talking about. Could you clarify that, not exactly in language I'd understand but in language he would. He told me this is what he thinks it is:


The electron's electronic dipole moment has been measured to be (0.07+/-0.07)*10^-26th E*CM

It's source is the electromagnetic force.

From the posting:

"An electric dipole moment occurs when the negative charges in a particle are separated from positive charges."

So the dipole moment is when positive charges are separated from negative charges. However, if they are separated they still have a net of zero. Only when you have a monopole (a particle with one charge) do you have a net of something other than zero, or a non-zero net dipole moment.

In the ordinary world, an example of a dipole would be a magnet. It has a positive and a negative. If you cut the magnet in half, the two separate halves will still have a positive and a negative. When you have a particle with just a negative pole or a positive pole you have a monopole particle.

I was only posting the +1 in jest as I don't know what the measurement would be. In fact, my hypothesis was based upon a rudimentary understanding of particle physics. Your friend would probably know a lot more.

The tricky thing about this post in my opinion is this:
"Which particle will be the first to be measured to have a non-zero dipole moment, and what will its value be?

There is no way to know ahead of time what the first of anything will be.

Got a response back today from the guy in charge. I guess my buddy got half of it right.

The uncertainty is correct but the value is consistent with zero. No
cigar.
