⇒ So, here, we can see a neutron decaying into a The corresponding Feynman diagram will be: This is a weak decay of the strange quark. It is an allowed diagonal change between quark generations. The Feynman diagram for the s to u transition is a combination of two quark-W vertices. The pion is derived from a same generation quark weak vertex.

L3: Feynman Diagram 2 Each Feynman diagram represents an amplitude (M). Quantities such as cross sections and decay rates (lifetimes) are proportional to |M|2.

The Feynman rules tell how to associate a number with each Feynman diagram.

FeynCalc is a Mathematica package for symbolic evaluation of Feynman diagrams and algebraic calculations in quantum field theory and elementary particle physics. Some features of FeynCalc are: Passarino-Veltman reduction of one-loop amplitudes to standard scalar integrals Since the correlation function associated with a disconnected Feynman diagram factorizes into those of the connected parts, the same is true for its Fourier transform. It will therefore be suﬃcient to set up the desired Feynman rules for connected diagrams in momentum space. We shall denote the external and internal points by the symbols x Step 2: For each Feynman diagram, label the four-momentum of each line, enforcing four-momentum conservation at every vertex. Note that arrows are. It is a Feynman diagram for the electron self energy, which will be calculated properly using quantum field theory in Lecture. III-5.
