I write a program to enable high accuracy measurements of momentum in bubble chamber slides from SLAC. Here is the lab. And here is the program.
I usually do graphics in LaTeX using Inkscape for the vector graphics. I explain how I do the Feynman diagrams, here.
There are only a certain number of interactions that may occur. They are described by the vertices of Ferynmans diagrams in the standard model. At each vertice several conservation laws must be met.
Quarks are fermions and come in six flavours: up, down, charm, strange, truth, and beauty. They have three fundamental quantum numbers: spin=1/2, charge=(-1/3) or (+2/3) depending on the flavour, and colour: (red | green | blue).
up:
spin=1/2
charge=+2/3
colour: (red | green | blue)
down:
spin=1/2
charge=-1/3
colour: (red | green | blue)
charm:
spin=1/2
charge=+2/3
colour: (red | green | blue)
truth:
spin=1/2
charge=-1/3
colour: (red | green | blue)
beauty:
spin=1/2
charge=-1/3
colour: (red | green | blue)
Quarks make up all baryons. Baryons can either have a charge of |1| or 0. Mesons are charge 0 made by a quarks and anti-quark pair.
