论文摘要
我们提出了一个相对论RNS粒子的自旋场的类似物,以将Ramond-Ramond状态描述为世界线上的“两粒子”激发。在自然代表空间上,我们确定了一个差异,其共同体学与RR场方程一致。然后,我们讨论在后者通过背景字段的变形中编码的非线性理论。我们还为此自旋场制定了一个Sigma模型,从中我们通过施加适当的约束来恢复RNS的成型。
We propose an analogue of spin fields for the relativistic RNS-particle in 4 dimensions, in order to describe Ramond-Ramond states as "two-particle" excitations on the world line. On a natural representation space we identify a differential whose cohomology agrees with RR-fields equations. We then discuss the non-linear theory encoded in deformations of the latter by background fields. We also formulate a sigma model for this spin field from which we recover the RNS-formulation by imposing suitable constraints.
