The big issue in choosing notation for a book on supersymmetry is whether to use a two-component or a four-component notation for spinors. The
standard texts on supersymmetry have opted for the two-component Weyl notation. I have chosen instead to use the four-component Dirac notation
except in the first stages of constructing the supersymmetry algebra and multiplets, because I think this will make the book more accessible to those
physicists who work on particle phenomenology and model building. It would be a pity to see the growth of a separate enclave of supersymmetry
specialists, who communicate well with each other but are cut off by their notation from the larger community of particle theorists.
