Manifestly supersymmetric quantization of superstring

我们证明低维双旋量（DS）超弦具有与纯旋量超弦 s 一致的物理谱，但其洛伦兹对称性是反常的。复制整个超空间坐标，我们在陪集超空间上构造了 DS 超弦。研究了具有通量的 AdS3×M7 的异质超引力中的 Killing 旋量方程，我们根据 M7 的 G 结构和固有挠场对 M7 进行了分类。 Neveu-Schwarz弦的无鬼定理在0图上直接证明。我们明确修正了修正立方开超弦理论的规范不变性，并表明物理传播器的极点位于 Virasoro 算子 L0 的零点。

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.
