| Abstract: | In this review we outline the spinor calculus technique and its applications. Together with the techniques of helicity amplitude, color-decomposition, duality, KLT relation and others, this technique is quite powerful in the study of non-Abelian gauge theory, supersymmetry, string theory and gravity/gauge theory relationship in the perturbative approach at tree-amplitude and loop-amplitude levels. |
