Feynman diagrams represent the mathematical expressions that describe the behavior of subatomic particles. Every shape represented in a diagram symbolizes a mathematical term. In this article we recommend two online services for creating Feynman diagrams. The nice thing about the web pages we recommend is the possibility of drawing several types of lines (fermion, gluon, electroweak force, etc.), so you can generate the graphics manually.
Feynman.Aivazis.com
With Feynman.Aivazis.com you can create Feynman diagrams from its interface developed in JavaScript. To generate the graphs, you'll see a large work area with a panel on each side. The right panel contains the elements divided into five categories with the option to insert text. The left panel holds all the other tools: naming the diagram, zoom, changing the grid size, and so on. The platform also supports drag-and-drop and the use of keyboard shortcuts:
- Alt + Click: To add a new anchor.
- Alt + Drag: To add a new propagator.
- Alt + Drag (drag) from an existing element: To add a branch.
- Delete/Backspace: To delete the selected element.
AidanSean.com
AidanSean.com offers an online tool for creating Feynman diagrams. Although the platform contains basic visual elements, it has a large number of very useful tools and functions to create the graphics. Unlike the service mentioned above, with AidanSean.com the mouse cursor transforms into a fully customizable brush.
With these two platforms you can easily draw Feynman diagrams and download them to your computer in several formats.
