AI 中文摘要
我们针对允许光滑α'→0 极限的背景，通过α'² 计算杂化模空间度量。凯勒势在此阶不变，但度量会因 Hull 联络的变形而得到修正，该变形混合了复结构和厄米特模。我们对此进行讨论并阐明扩张丛、F 项、D 项和弦导出模空间度量的作用。
英文摘要
We compute the heterotic moduli-space metric through $α'^2$ for backgrounds admitting a smooth $α'\to0$ limit. The Kaehler potential is unchanged when written in an appropriate field basis suggested by the ten-dimensional supersymmetry equations, while the metric receives $α'^2$ corrections. We discuss this and clarify the roles of the extension bundle, F-terms, the D-terms and the string-derived moduli space metric.
