论文摘要
我们首次报告说，在4-torus或等效的IIA字符串上被K3上压实的杂弦中，以固定保守指控为旋转的黑色字符串熵的领先$α'$校正可能为负。这进一步意味着对极端旋转弦的质量的校正是积极的，与弱重力猜想的标准期望相反。我们的结果表明，由于高阶操作员而导致的熵转移阳性的有效性取决于有效的现场理论分析中先前省略的其他因素。
We report for the first time that in heterotic string compactified on 4-torus or equivalently IIA string compactified on K3, the leading $α'$ corrections to the rotating black string entropy at fixed conserved charges can be negative. This further implies that the correction to the mass of extremal rotating string is positive, opposite to the standard expectation from the weak gravity conjecture. Our result suggests that the validity of positivity of entropy shift due to higher order operators depends on other factors omitted previously in the effective field theory analysis.
