本文在S-矩阵程序框架下证明了N = 8超引力（SUGRA）和N = 4超Yang-Mills（SYM）树级振幅之间的超对称Kawai-Lewellen-Tye（KLT）关系，特别是我们没有使用弦理论或相应理论的显式拉格朗日形式.我们的超对称KLT关系自然统一的非超对称KLT关系和新发现的规范理论的身份，并产生更多的身份涉及标量和费米子的振幅。我们还指出，这些新发现的恒等式可以用来从（n-3）约化螺旋度基!再往下
In this short note, we prove the supersymmetric Kawai-Lewellen-Tye (KLT) relations between N = 8 supergravity (SUGRA) and N = 4 super Yang-Mills (SYM) treelevel amplitudes in the frame of S-matrix program, especially we do not use string theory or the explicit Lagrangian form of corresponding theories. Our supersymmetric KLT relations naturally unify the non-supersymmetric KLT relations and newly discovered gauge theory identities and produce more identities for amplitudes involving scalars and fermions. We point out also that these newly discovered identities can be used to reduce helicity basis from (n − 3)! further down.
