$α'$的奇怪故事-更正
The Odd story of $α'$-corrections
摘要：
$α'$ -变形的框架状双场论（DFT）是DFT的T-对偶和规范不变的推广，其中广义Green-Schwarz变换提供了固定高阶导数修正的规范原理。它包括玻色子弦和杂化弦低能有效作用量的一阶$α'$修正和Hohm-Siegel-Zwiebach $α'$几何的一阶修正。在这里，我们衡量这个理论和参数化的框架，一个两种形式，一个介子，规范矢量和标量场。这导致了一个统一的框架，扩展了以前的建设，包括所有的对偶约束的相互作用在通用（规范/超）引力有效场论在任意数量的维度，一阶$α'$。
英文摘要：
The $α'$-deformed frame-like Double Field Theory (DFT) is a T-duality and gauge invariant extension of DFT in which generalized Green-Schwarz transformations provide a gauge principle that fixes the higher-derivative corrections. It includes all the first order $α'$-corrections of the bosonic and heterotic string low energy effective actions and of the Hohm-Siegel-Zwiebach $α'$-geometry. Here we gauge this theory and parameterize it in terms of a frame, a two-form, a dilaton, gauge vectors and scalar fields. This leads to a unified framework that extends the previous construction by including all duality constrained interactions in generic (gauged/super)gravity effective field theories in arbitrary number of dimensions, to first order in $α'$.
