Is there ghost and tachyon free bounce in UV complete gravity theory?
Hao Hu, Alexey S. Koshelev, Abhishek Naskar
Analytic infinite derivative gravity theories provide a renormalizable and ghost-free description of gravity around covariantly constant backgrounds. These theories can have non-si…

Convergent sum of EFT corrections to Schwarzschild metric requires UV locality
Yang Liu, Alexey S. Koshelev, Anna Tokareva +1
Corrections to vacuum black hole solutions of general relativity (GR) are considered in an effective field theory (EFT) framework, perturbatively in EFT coefficients, focusing on t…
