关于弱引力猜想的一种新的解释

A New Spin on the Weak Gravity Conjecture

Lars Aalsma, Alex Cole, Gregory J. Loges, Gary Shiu

摘要:

弱引力猜想的温和形式指出,量子或更高阶导数的修正应该会减少固定电荷的大型极端带电黑洞的质量。这使得极端黑洞可以衰变,除非有对称性(如超对称性)的保护。我们重新制定这个猜想作为一个完整的条件,有效的应力张量捕获量子或更高的导数校正的效果。除了带电黑洞,我们还考虑旋转BTZ黑洞,并表明,这一条件是满足的$c$定理的后果,证明旋转版本的弱引力猜想。我们也将我们的结果应用到一个五维的提升黑弦与更高的导数校正。提升的黑弦有一个$\text{BTZ}\times S^2$近视界几何,在卡鲁扎-克莱因约化后,描述了一个四维带电黑洞。结合自旋和荷电弱引力猜想,我们得到了比单独从荷电黑洞得到的更强的五维Wilson系数的正界.

英文摘要:

The mild form of the Weak Gravity Conjecture states that quantum or higher-derivative corrections should decrease the mass of large extremal charged black holes at fixed charge. This allows extremal black holes to decay, unless protected by a symmetry (such as supersymmetry). We reformulate this conjecture as an integrated condition on the effective stress tensor capturing the effect of quantum or higher-derivative corrections. In addition to charged black holes, we also consider rotating BTZ black holes and show that this condition is satisfied as a consequence of the $c$-theorem, proving a spinning version of the Weak Gravity Conjecture. We also apply our results to a five-dimensional boosted black string with higher-derivative corrections. The boosted black string has a $\text{BTZ}\times S^2$ near-horizon geometry and, after Kaluza-Klein reduction, describes a four-dimensional charged black hole. Combining the spinning and charged Weak Gravity Conjecture we obtain positivity bounds on the five-dimensional Wilson coefficients that are stronger than those obtained from charged black holes alone.
