So, in the field of particle physics there are a kind of diagrams called Feynman diagrams. Please search "Feynman diagrams" in google to see how they are if you don't know them.
I am interested in drawing Feynman diagrams in inkscape, which will require, for general purposes, a set of basic "patterned curves". My present question has two purposes:
- There are some "patterned curves" that I really do not know how to create in inkscape; these are presented and indicated below.
- I am hoping this question will serve as a reference for any one else interested in drawing Feynman diagrams with Inkcape.
The following is a list of the curves (and respective "names") used when creating Feynman diagrams, with a description of how I create it. Please feel free to modify any instruction you consider confusing (I have very few background on Inkscape), or you think there is a better way to do it:
1.- Straight lines:
- Fermionic line:
Select "Bezier Curve". Holding down "ctrl", then "right-click" and trace a horizontal solid line. In order to add arrow in the middle, select the line and then the option "Edit paths by nodes"; double click in the middle of the line in order to add a node just there. Then go to "Object" and select "Fill and Stroke...". In the "Stroke style" tab, select a middle arrow in "Markers"
- Scalar line:
Create a fermionic line. Then in the "Stroke style" tab, select a dashed pattern in the "Dashes" option.
- Gluon line:
This line I build according to the method provided by the user "Beenwu" (here) on YouTube. Go to "Extensions", then "Render", then "Parametric Curves...". Enter the following values. With the tool "Create rectangles and squares" create a rectangle, and then click on "Apply".
- Vector line:
Analogous to the gluon case, only this time you have to enter different parameters indicated in the above link.
2.- Curved lines
I would like to draw also the four above lines but "curved"; for instance, something like this:
I can use the tool "Bezier curve" to draw fermionic and scalar curved lines, but I do not know how to do it for gluon and vector curved lines.
3.- Loops: the same four above lines but in the form of a loop, i.e.
I draw the fermionic and scalar loops with the tool "Create circles, ellipses and arcs", but not shure how to add those two arrows like in the above image.
I do not know how to draw those gluon and vector loops.
