Probing effective field theory corrections with quasinormal modes and gravitational lensing in Reissner–Nordström black holes

Abstract Effective field theory (EFT) provides a systematic framework for parametrizing possible higher-energy corrections to general relativity through higher-curvature interactions. In this work, we investigate gravitational lensing in both weak- and strong-field regimes for EF...
