There will be one undetermined four-momentum for each loop. The Feynman rules tell how to associate a number with each Feynman diagram. There are several basic rules from which the number is constructed: Rule 0: a factor of i. 1997-09-23 The resulting Feynman rules are summarized in the following table: = i p= m+i = i p=+m p2 m2 +i (3) = i g p2 +i (Feynman gauge) (4) = ie Q (Q= 1 for the electron, Q= 2=3 for the u-quark, etc.) (5) Let us start by considering a simple QED process, e+e ! (for simplicity we shall always as-sume m= 0): = D1 +D2 (6) The total amplitude M is given by: i e2 M 2021-04-11 Momentum space Feynman rules Choose an arbitrary orientation of every line.

These diagrams, therefore, portray what is “really” happening, and provide a convenient way to catalogue the various possible processes of creation, annihilation, and exchange. The key points of a Feynman diagram are the “vertices,” representing those spacetime points at which (in this example) photons are created or absorbed. ⇒ 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 4 Golden rules for decays and scatterings 11 5 Feynman diagrams 13 Notes for the exercises at theAdriatic School on Particle Physics and Physics Informatics, 11 – 21 Sep 2001, Split, Croatia ykkumer@phy.hr 1 arXiv:1602.04182v1 [physics.ed-ph] 8 Feb 2016 Like electrical circuit diagrams, every line in the diagram has a strict mathematical interpretation.

We can define this integral by a perturbation expansion. This can be expressed in terms of Feynman diagrams, and for each diagram there is an amplitude given by the Feynman rules. I see that, formally, ##(1)## takes the form So the basic Feynman rules to calculate things in the MSSM are not changed, but there are additional sparticles to play with.
