I wonder if someone could explain what is known about electron capture in which a proton captures an electron which then becomes a neutron? I have read that a proton which has two up quarks and a single down quark will have the the creation and destruction of multiple quark - antiquark pairs within the diameter of the proton happening.
But an electron is also a fundamental particle so, what happens there?
Does for example, the electron knock out one of the up quarks which allows a down quark - antidown quark pair to take advantage of the situation? Such that, the down quark remains in the particle and the antidown quark goes away with the up quark as a meson with up quark - antidown quark character? What happens to the electron though? It is a fundamental particle and cannot be destroyed correct?
thanks
