N = 2超引力中的非线性自对偶性

Nonlinear self-duality in N = 2 supergravity

Sergei M. Kuzenko

摘要:

对于四维Abel向量超多重态与N = 2超引力耦合的非线性模型,我们给出了表示U(1)对偶旋转不变性的自对偶方程。在平坦空间的极限下,该方程简化为在hep-th/0001068中提出的N = 2自对偶方程。我们还给出了一个例子的自对偶局部超对称模型包含一个更高的衍生扩展的Born-Infeld行动在组件水平。

英文摘要:

For nonlinear models of an Abelian vector supermultiplet coupled to N = 2 supergravity in four dimensions, we formulate the self-duality equation which expresses invariance under U(1) duality rotations. In the flat space limit, this equation reduces to the N = 2 self-duality equation proposed in hep-th/0001068. We also give an example of a self-dual locally supersymmetric model containing a higher-derivative extension of the Born-Infeld action at the component level.
