Natural Science Forum / Physics / Particle Physics / September 2004The Electron
The electron has three quanta of charge. How can this be since the electron is small and like charge repels? | The electron has three quanta of charge. | How can this be since the electron is small and like | charge repels? Doubtful. Maybe the real quantum of charge is +,- sqrt(hbar*c). Then electrons also have fractional charge of the charge quantum. Fermions can't be isolated from the quantum vacuum. So the electron is really not much different than quarks that can't be isolated.

If the electron is a fundamental particle with no discernable internal structure, how does it carry a negative charge? What mechanism links the charge to the physical mass of the electron?

Do a google search. You will find plenty. IMHO, the structure of an electron is not "internal". When you count the quantum vacuum, and you really have to, the structure is external.

I have not come across such a cocncept as quantum vacuum for an electron. And if a proton is just composed of quarks and gluons, what causes gravity in hydrogen? Anyway, God bless you, FrediFizzx!

The universe has many more particles than this, and that reveals the weaknesses of trying to learn things from references found on the web. At the very least, this list ignores the particles that are the mediators of the interactions between the above particles. Photons for electromagnetic interaction, W & Z particles for weak interaction, gluons for the strong interaction, gravitons for the gravitational interaction. Call the electron, the two quarks, and the neutrino fermions, and call the others bosons. At an intuitive level, what a fermion is can be described by what happens when it runs into boson. The strength of the interaction is what we mean by "charge". So there is a "charge" associated with interacting with a photon, another "charge" associated with interacting with a gluon, another "charge" associated with interacting with a graviton (which charge we sometimes call mass). If a fermion has a "charge" value of zero of a certain kind, then it doesn't directly interact with that boson. So far, we know that quarks interact with photons, gluons, W&Z bosons and gravitons. Electrons interact with photons, W&Z bosons, and gravitons. Neutrinos interact with W&Z bosons and (until recently we thought) that's it. (Neutrinos may interact with gravitons, as it turns out.) In a very real sense, if a fermion were conceived that didn't interact with any boson, then by definition it wouldn't exist! For the experienced, I know I'm glossing over a lot. But by and large, this gets the point across, I hope. PD |
