α '中一阶有效action的杂化超弦的O(n,n)不变性和Wald熵公式

O(n,n) invariance and Wald entropy formula in the Heterotic Superstring effective action at first order in alpha'

Tomas Ortin

摘要:

我们在$α'$中对完全Bergshoeff-de Roo形式的杂合超弦有效作用量进行了一阶环面紧化。降维的行动是在一个明显的O(n,n)不变的形式,我们使用它来推导出一个明显的O(n,n)不变的Wald熵公式,然后我们使用它来计算熵的$α'$校正,4维,4-电荷,静态,极端,超对称黑洞。

英文摘要:

We perform the toroidal compactification of the full Bergshoeff-de Roo version of the Heterotic Superstring effective action to first orderin $α'$. The dimensionally-reduced action is given in a manifestly-O(n,n)-invariant form which we use to derive a manifestly-O(n,n)-invariant Wald entropy formula which we then use to compute the entropy of $α'$-corrected, 4-dimensional, 4-charge, static, extremal, supersymmetric black holes.
