II型定向褶皱中非几何通量的量纲氧化

Dimensional Oxidation of Non-geometric Fluxes in Type II Orientifolds

Ralph Blumenhagen, Xin Gao, Daniela Herschmann, Pramod Shukla

摘要:

根据双场论的最新进展,重新讨论了非几何通量弦紧化的某些方面。在重新推导这些通量的一般形式后,我们考虑了所提出的通量诱导四维有效超势,并将其诱导标量势氧化为十维作用量中的项。这种分析是独立进行的一个明确的环形IIA型和它的T-双IIB型orientifold。我们详细地表明,这种自底向上的方法的结果是兼容的规范超重力激发通量制定的双场论行动在NS-NS和R-R部门。

英文摘要:

Some aspects of string compactifications with non-geometric fluxes are revisited in the light of recent progress in double field theory. After rederiving the general form of these fluxes, we consider the proposed flux induced four-dimensional effective superpotential and oxidize its induced scalar potential to terms in a ten-dimensional action. This analysis is performed independently for an explicit toroidal type IIA and its T-dual type IIB orientifold. We show in detail that the result of this bottom-up approach is compatible with the gauged supergravity motivated flux formulation of the double field theory action in both the NS-NS and the R-R sector.
