Were in the neutron is the electron?

Perhaps the proton is a spheare and the electron is a dot!

Is the electron in the middle of the neutron?

No; you have a swarm of quarks, at least three (u, d, d). Then a quark d emits a W- particle, turning himself into a quark u. The W- can not survive because has not enough energy, so it desintegrates into an electron plus a (anti-)neutrino.

is there any explanation of how the W- particle disintegrates into an electron and electronantineutrino?

[arivero]

because it can.

IE there is not explication, just experimental input we translate into some mathematical terms in the standard model.

Now, a composite theory for the force bosons, such as W, should predict a specific kind of distribution of spin, momenta and energy when the particle desintegrates or scatters. I guess most possibilities are already ruled out.

Purge yourselves of such classical depictions. As far as quantum theory is concerned, particles et al are simply entities/phenomena, that interact in given, mathematically defined, ways. They do not correspond to our billiard ball experiences.

Well, the "simplest" explanation would be that these are the most likely particles which it can decay into, based on mass/energy considerations, charge conservation, spin conservation, lepton/baryon number, etc...

In a nutshell, this is what the electroweak gauge theory will tell you. I suppose this is more of a "why" explanation. As for the "how" -- ask yourself "how" the wavefunction knows to collapse to a particular eigenstate... (hint: no one knows!).

this is really annoying because the physics book says the neutron does decay because it does, so no answer to "why" and "how" really... just like the question: what is charge?
