有证据表明，人们可以计算树级的超级杨米尔斯振幅使用连接或完全断开的曲线在扭量空间。我们给出了一个部分的解释，这两个计算之间的等价性，通过显示，它们都可以减少到相同的积分在一个模空间的奇异曲线，受一些假设的选择的集成轮廓。我们还制定了一类新的“中间”处方计算相同的振幅。
There is evidence that one can compute tree-level super Yang-Mills amplitudes using either connected or completely disconnected curves in twistor space. We give a partial explanation of the equivalence between the two computations, by showing that they could both be reduced to the same integral over a moduli space of singular curves, subject to some assumptions about the choices of integration contours. We also formulate a class of new “intermediate” prescriptions to calculate the same amplitudes.
