标题： Half-maximal consistent truncations using exceptional field theory

摘要： 我们展示了如何利用例外场理论将10维和11维超引力一致截断到七维，构造出半极大情形。这一过程产生了一个七维的半极大规范超引力，它耦合了$n$个矢量多重态，并且通常有$n \neq 3$个规范群。我们还展示了这些技术如何被用来将例外场理论约化到异质双重场理论。 显示英文摘要

摘要： We show how to construct half-maximal consistent truncations of 10- and 11-dimensional supergravity to seven dimensions using exceptional field theory. This procedure gives rise to a seven-dimensional half-maximal gauged supergravity coupled to $n$ vector multiplets, with $n \neq 3$ in general. We also show how these techniques can be used to reduce exceptional field theory to heterotic double field theory.
