What does a Feynman diagram show?
In theoretical physics, a Feynman diagram is a pictorial representation of the mathematical expressions describing the behavior and interaction of subatomic particles. Feynman diagrams can represent these integrals graphically.
How to draw Feynman diagrams on LaTeX?
The feynmf package lets you easily draw Feynman diagrams in your LaTeX documents. All you need to do is specify the vertices, the particles and the labels, and it will automatically layout and draw your diagram for you.
How do I install TikZ Feynman?
Firsty, you’ll need to obtain the package files from either project page or CTAN. Next, you’ll need to locate your local TEXMF tree, and there are instructions for that in other questions (Linux / Unix, Windows). Note that TikZ-Feynman contains a few extra files in addition to the usual .
Are Feynman diagrams still used?
Feynman. Introduced during the development of the theory of quantum electrodynamics as an aid for visualizing and calculating the effects of electromagnetic interactions among electrons and photons, Feynman diagrams are now used to depict all types of particle interactions.
How do I use TIKZ in LaTeX?
Using TikZ in a LaTeX document requires loading the tikz package:
- sepackage{tikz} somewhere in the preamble.
- setikzlibrary{⟨list of libraries separated by commas⟩}
- \begin{tikzpicture}[⟨options⟩] ⟨tikz commands⟩ \end{tikzpicture}
- \tikz[⟨options⟩]{⟨tikz commands⟩}
How do I use TIKZ in latex?
How do you make a commutative diagram in latex?
To load this package in LATEX, type sepackage{tikz-cd} or load TikZ and then type setikzlibrary{cd} This package is compatible with other TEX formats as well. See §1.5 and §1.6. The basic tool to create a commutative diagram is the following environment.
What was Richard Feynman IQ?
Nobel Prize-winning physicist Richard Feynman talked about getting a 124 on the only IQ test he ever took. 124 is plenty bright — but Feynman was one of the greatest scientists of the 20th century; 124 is about 30 points off the lowest remotely plausible value.
How to generate Feynman diagrams in latex?
More recently, a new package called Ti k Z-Feynman has been published which uses Ti k Z in order to generate Feynman diagrams. Ti k Z-Feynman is a LaTeX package allowing Feynman diagrams to be easily generated within LaTeX with minimal user instructions and without the need of external programs.

What are the internal lines in Feynman diagram?
Anatomy of Feynman Diagrams External lines (visiblerealparticles) Spin 1/2 Particle Incoming Outgoing Antiparticle Incoming Outgoing Spin 1 Particle Incoming Outgoing Internal lines (propagators;virtualparticles)
What is Ti K Z-Feynman?
Ti k Z-Feynman is a LaTeX package allowing Feynman diagrams to be easily generated within LaTeX with minimal user instructions and without the need of external programs. It builds upon the Ti k Z package and its graph drawing algorithms in order to automate the placement of many vertices.
