论文摘要
在本文中，我们研究了$ \ Mathcal {n} = 1 $超级时空的双重电荷。所考虑的动作是通常的超级加重行动，具有拓扑贡献。这是Nieh-Yan术语和自由Rarita-Schwinger字段的磁性项。通过协变相空间形式主义的方法，我们构建了与超对称性，差异和洛伦兹变换的共轭。行动中的附加任期将导致对这些指控的新贡献。磁性差异电荷相当于先前发现的重力，而双重超对称电荷是新的，并且没有出现在游离的Rarita-Schwinger场中。双Lorentz的费用有助于使前两项正规化。我们发现，用于超级重力的渐近对称性组只能包括全球定义明确的超级旋转。
In this paper we study the dual charges of $\mathcal{N}=1$ supergravity in asymptotically flat space-time. The action considered is the usual supergravity action with a topological contribution. This is the Nieh-Yan term and the magnetic term of the free Rarita-Schwinger field. Through methods of the covariant phase space formalism we construct the charges conjugate to supersymmetry, diffeomorphism and Lorentz transformations. The additional term in the action will lead to new, non-vanishing contributions to these charges. The magnetic diffeomorphism charges are equivalent to the ones previously found for gravity, while the dual supersymmetric charges are new and do not appear for the free Rarita-Schwinger field. The dual Lorentz charges serve to regularize the previous two. We find that the asymptotic symmetry group for supergravity can only include globally well-defined super-rotations.
