Manifestly supersymmetric quantization of superstring

我们证明了低维双旋量（DS）超弦具有与纯旋量超弦重合的物理谱，但它的洛伦兹对称是反常的。复制整个超空间坐标，我们在余集超空间上构造了DS超弦。研究了具有通量的AdS3×M7异质超重力中的杀死旋量方程，我们根据它们的g结构和本征扭转对M7进行了分类。在0图中直接证明了Neveu-Schwarz弦的无鬼定理。我们明确地固定了修正三次开放超弦理论的规范不变性，并证明了物理传播子在Virasoro算子L0的零点处具有极点。

We showed that the lower-dimensional double-spinor(DS) superstring has such a physical spectrum that coincides with the pure-spinor superstring s but its Lorentz symmetry is anomalous. Duplicating the whole superspace co-ordinates, we constructed the DS superstring on the coset-superspace. Investigating the Killing spinor equations in the Heterotic supergravity for AdS3×M7 with fluxes, we classified M7 based on their G-structures and intrinsic torsions. The no-ghost theorem for Neveu-Schwarz string was directly proved in 0-picture. We explicitly fixed the gauge invariance of modified cubic open superstring theory and showed that the physical propagator has poles at the zeros of the Virasoro operator L0.
