Introduction. ⇒ Feynman Diagrams are pictorial representations of the interactions of subatomic particles. ⇒ For example, this shows a Feynman Diagram of beta (β -) decay (see our notes on nuclear equations if you have not done so already): ⇒ Usually, Feynman Diagrams are read from left to right. ⇒ So, here, we can see a neutron decaying into a

Feynman diagrams are graphical ways to represent exchange forces. Here are two representations of beta decay: note that the decay of a particle start with that particle on the lower left - remember that time is the y axis (starts at the bottom left of the diagram!) and in 2005-08-31 Like electrical circuit diagrams, every line in the diagram has a strict mathematical interpretation. For details of Feynman diagram calculation, take a Advanced Quantum or 880.02 course see Grifﬁths (e.g. sections 6.3, 6.6, and 7.5) Bjorken & Drell (Relativistic Quantum Mechanics). Feynman Diagrams µ decay € e+e−→µ+µ− scattering It is the double beta decay without neutrino emission, or neutrinoless double beta decay ().

At the fundamental level (as depicted in the Feynman diagram below), this is due to the conversion of a down quark to an up quark by emission of a W− boson;

Feynman diagrams are intended to help us think about what happens but they cannot represent anything like a true image of interactions that take place in 3 dimensions. We use this code on the diagrams, you might find different codes used by some publishers. This one code is used by the Institute of Physics and is common, but not universal.
