EFT Corrections to Majumdar-Papapetrou Black Holes

Abstract

Recent studies on extremal black holes within effective field theories (EFT) of gravity have revealed an intriguing phenomenon: tidal forces near the horizon experience significant enhancement due to EFT corrections, potentially leading to a breakdown of the EFT framework. In this work, we investigate this effect in a two-black-hole Majumdar-Papapetrou spacetime modified by four-derivative EFT correction terms. Our analysis shows that while the scaling exponents, which measure the strength of the tidal forces near the horizon, remain unchanged under EFT corrections in $D=4$, they decrease for higher dimensions, enhancing the near-horizon tidal forces. We find an expression for the EFT corrections to the scaling exponents till $D\le 10$ and demonstrate that the metric corrections can be structured such that only the near-horizon $Ad{S}_2$ throat undergoes angle-dependent modifications, while the transverse $S^{D-2}$ sector remains unaffected.
