N=4超引力中的轴对称规范及其高维起源

Axionic symmetry gaugings in N=4 supergravities and their higher-dimensional origin

Jean-Pierre Derendinger, P. Marios Petropoulos, Nikolaos Prezas

摘要:

我们研究了通过测量轴位移和轴重标度对称性得到的四维N=4超引力。我们制定这些理论使用的机械嵌入张量,全规范代数的特点,并讨论了这个家庭的规范超引力的几个具体特点。我们表现出特别是一个广义的大规模矢量和大规模的两种形式在四维之间的对偶性,继承了测量的移位对称性。我们表明,这些理论可以推导出从更高的维度由Scherk-Schwarz减少,扭曲相对于一个非紧凑的对称性是必需的。四维广义对偶在识别高维升元中起着至关重要的作用。

英文摘要:

We study the class of four-dimensional N=4 supergravities obtained by gauging the axionic shift and axionic rescaling symmetries. We formulate these theories using the machinery of embedding tensors, characterize the full gauge algebras and discuss several specific features of this family of gauged supergravities. We exhibit in particular a generalized duality between massive vectors and massive two-forms in four dimensions, inherited from the gauging of the shift symmetry. We show that these theories can be deduced from higher dimensions by a Scherk-Schwarz reduction, where a twist with respect to a non-compact symmetry is required. The four-dimensional generalized duality plays a crucial role in identifying the higher-dimensional ascendent.
