论文摘要
我们使用$ O（d，d）$ - 从双场理论中熟悉的超级强度的协变配方，以找到第一个$α'$ - 校正到（单型）同质性杨巴克斯特（yb）玻色弦字符串的变形。此结果的一种特殊情况给出了$α'$ - 对TST转换的校正。在合适的方案中，校正完全来自诱导的异常双Lorentz转换，这是使在YB变形相等时获得的两个Vielbeins所需的。正如我们所讨论的那样，这应该更普遍，特别是对于阿贝利安和非阿布莱的T偶性。
We use the $O(d,d)$-covariant formulation of supergravity familiar from Double Field Theory to find the first $α'$-correction to (unimodular) homogeneous Yang-Baxter (YB) deformations of the bosonic string. A special case of this result gives the $α'$-correction to TsT transformations. In a suitable scheme the correction comes entirely from an induced anomalous double Lorentz transformation, which is needed to make the two vielbeins obtained upon the YB deformation equal. This should hold more generally, in particular for abelian and non-abelian T-duality, as we discuss.
