The 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.

Nov 6, 2024 · Beta-plus decay can be represented on a Feynman diagram with the W+ boson as the exchange particle. The proton acts on the electron during electron capture. This is shown …

Through electron capture, an electron is absorbed by a proton within a nucleus The proton decays into a neutron and a W exchange particle. The W exchange particle interacts with the electron …

Français : Le diagramme de Feynman pour la capture électronique. Le quark up du proton, après la capture d'un électron, se désintègre en quark down créant ainsi un neutron, accompagné …

To draw a Feynman diagram and determine whether a process is allowed, follow the five basic steps below: Write down the initial and final state particles and antiparticles and note the quark …

We illustrate the most basic use of Feynman diagrams with a few examples. Consider first the electromagnetic scattering process e. −µ−→e−µ−in Figure 1. We think of time running from left …

Feynman diagrams are graphical ways to represent exchange forces. Each point at which the lines come together is called a vertex, and at each vertex we must conserve charge, baryon …

Jan 19, 2024 · Diagram E : This represents electron capture. A proton captures an electron and becomes a neutron and an electron neutrino. Diagram F : This represents a neutrino-neutron …

Remember - these diagrams aren't just pictures; they're a shorthand for precise mathematical calculations. Each line, each vertex, each crossing has specific rules. The beauty is that these …
