我们在CP3|4的B模型上用扭曲弦理论计算了共形超引力子的最大螺旋度破坏(MHV)树振幅。仿射Kac-Moody电流(Sugawa应力-能量张量)中双线性的相关器可以产生这些幅度。我们与开弦形式的扭弦理论的结果进行了比较。我们还从应力-能量张量和电流之间的关联器计算了引力子和胶子的MHV树振幅。
We use the twistor-string theory on the B-model of CP 3|4 to compute the maximally helicity violating(MHV) tree amplitudes for conformal supergravitons. The correlator of a bilinear in the affine Kac-Moody current(Sugawara stress-energy tensor) can generate these amplitudes. We compare with previous results from open string version of twistor-string theory. We also compute the MHV tree amplitudes for both gravitons and gluons from the correlators between stress-energy tensor and current.
