This all meshes with the idea that force particles are just weird quantum objects which mediate forces. In the particle picture, the interactions can be conveniently described by Feynman diagrams, which may be regarded either as branch diagrams of the perturbation expansion or as collision diagrams. The derivation of the transfer expressions can then be reduced to a few general rules for the construction of the diagrams and the associated collision cross sections.

It is a Feynman diagram for the electron self energy, which will be calculated properly using quantum field theory in Lecture. III-5. Lagrangian derivation. 5. Page 6 Draw a Feynman diagram of the process and put momenta on each line consistent with momentum conser- vation. 2.

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 transition rate for a process can be calculated with time dependent perturbation theory using Fermi’s Golden Rule:

Electroweak At the same time, the Feynman rules for gravity are very complicated, although the resulting amplitudes do not have the same complications.

Feynman Diagrams and Cutting Rules J.S. Rozowsky1 Department of Physics, University of California at Los Angeles, CA 90095-1547 Abstract We show how Feynman diagrams may be evaluated to take advantage of recent developments in the application of Cutkosky rules to the calculation of one-loop am-plitudes.

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).

At the most fundamental level, the strong force is an exchange force between quarks mediated by gluons.The use of Feynman diagrams to visualize the strong interaction involves primitive vertices with quarks and gluons. A diagram is constructed when the lines are connected together in pairs to form edges of a graph, with no stray lines leaving. The general procedure is to ﬁrst ﬁgure out which diagrams are relevant to the problem being solved, and then use some Feynman rules to calculate a value for each diagram. The Feynman rules tell us how to go from a diagram to the corresponding matrix element (or amplitude) which is necessary to calculate σσσσand ΓΓΓ. There are 3 kinds of ingredients: external lines, internal lines and propagators.
