Electron Proton Collisions and Electron Capture
What is the difference between electron capture, and electron-proton collions?
My textbook has the feynman diagram of electron capture as a proton decaying into a neutron, and the proton emmiting a W+ boson, which is recieved by an electron, which then decays into a neutrino.
However, the electron proton collision has an electron decaying into a neutrino and the electron emitting a W- boson, which the proton recieves, which decays into a neutron.
Obviously, rather than proton and neutron, up and down quarks can be used in the above.
Why is there this difference in the two processes?

That's a helluva intro physics class, eh? :)
Seeing as how I hate particle physics, my answer is probably a bit biased, but I would assume the reason is because IT'S ALL A BUNCH OF BS >_>
seriously though, I know electron capture is an event that takes place in the nuclei of atoms, so I would wager the electron-proton collision is a similar event that takes place outside the nucleus. Assuming there IS a difference besides the very fundamental one you described
