关于二维N=(4,4)超空间超引力

On 2D N=(4,4) superspace supergravity

Gabriele Tartaglino-Mazzucchelli

摘要:

本文综述了近年来在研究二维N=(4,4)物质耦合超引力的超空间公式中所获得的一些结果。对于由最小超引力多重态描述的超空间几何,我们首先描述如何通过使用arXiv:0907.5264中的“外质”超形式技术将手征积分减少到分量,然后我们回顾arXiv:0911.2546中引入的双投影超空间形式主义。在此基础上,我们详细讨论了曲双投射形式,给出了一个新的结果:协变I型扭曲多重态约束在权-(-1,-1)双投射超场中的解。

英文摘要:

We review some recent results obtained in studying superspace formulations of 2D N=(4,4) matter-coupled supergravity. For a superspace geometry described by the minimal supergravity multiplet, we first describe how to reduce to components the chiral integral by using ``ectoplasm'' superform techniques as in arXiv:0907.5264 and then we review the bi-projective superspace formalism introduced in arXiv:0911.2546. After that, we elaborate on the curved bi-projective formalism providing a new result: the solution of the covariant type-I twisted multiplet constraints in terms of a weight-(-1,-1) bi-projective superfield.
