WebFeynman Diagrams for Beginners Krešimir Kumerickiˇ y Department of Physics, Faculty of Science, University of Zagreb, Croatia Abstract We give a short introduction to Feynman … WebThe leading-order Feynman diagrams for electron capture decay. An electron interacts with an up quark in the nucleus via a W boson to create a down quark and electron neutrino. Two diagrams comprise the leading (second) order, though as a virtual particle, the type (and charge) of the W-boson is indistinguishable.

"WebThe diagrams show the possible ways in which particles can interact with each other through the exchange of other particles. For example, a Feynman diagram can show how two electrons repel each other through the exchange of a photon, or how a proton can decay into a neutron, a positron, and a neutrino through the exchange of a W boson.
