非几何通量的十维action

A ten-dimensional action for non-geometric fluxes

David Andriot, Magdalena Larfors, Dieter Lust, Peter Patalong

摘要:

利用广义复几何的启发,通过改变场变量,改写了十维超引力的NSNS拉格朗日量。我们得到了一个新的度量和一个反对称的双向量场,它导致了一个十维版本的非几何Q通量。鉴于涉及全球方面的非几何的情况下,我们规定使用这个新的拉格朗日,其相关的行动是定义良好的一些例子在这里调查。这使我们能够执行标准的降维,并恢复通常的贡献的Q通量的四维标量势。扩展这项工作,包括R-通量进行了讨论。本文还对非几何作了简要的回顾。

英文摘要:

The NSNS Lagrangian of ten-dimensional supergravity is rewritten via a change of field variables inspired by Generalized Complex Geometry. We obtain a new metric and dilaton, together with an antisymmetric bivector field which leads to a ten-dimensional version of the non-geometric Q-flux. Given the involved global aspects of non-geometric situations, we prescribe to use this new Lagrangian, whose associated action is well-defined in some examples investigated here. This allows us to perform a standard dimensional reduction and to recover the usual contribution of the Q-flux to the four-dimensional scalar potential. An extension of this work to include the R-flux is discussed. The paper also contains a brief review on non-geometry.
