【摘要】 介绍了旋量算法技术及其应用.这个技术与螺旋度振幅、色分解、对偶性、KLT关系等技术相结合,可以在微扰论的树图和圈图水平上,对非阿贝尔规范理论、超对称、弦理论及引力-规范理论对偶等方面的研究发挥重要作用.更多还原

【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.更多还原
