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 received 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?
Thanks
