标题： On the stability of Einsteinian Cubic Gravity black holes in EFT

摘要： 在本文中，我们重新审视了发表在arXiv:2305.07217中的关于爱因斯坦三次引力（ECG）中静态且球对称黑洞的奇数宇称扰动的分析。我们表明，额外传播的模态的质量总是远高于该理论的截止值。因此，与那篇论文中的说法相反，在有效场论范围内，ECG黑洞仍然保持稳定。我们针对一般的三次理论进行了相同的分析，表明ECG的结果在这方面并不特殊。我们借此机会对ECG及其推广的作用、用途和局限性进行了一些澄清。 显示英文摘要

摘要： In this note we revisit the analysis performed in arXiv:2305.07217 of odd-parity perturbations around static and spherically symmetric black holes in Einsteinian Cubic Gravity (ECG). We show that the additional propagating modes always have masses much above the cutoff of the theory. Therefore, contrary to what is claimed in that paper, the ECG black holes remain stable within the effective field theory regime. We consider the same analysis for a general cubic theory, showing that the ECG results are not special in this regard. We use the occasion to make some clarifications on the role, uses and limitations of ECG and its generalizations.
