In more realistic scenarios, however, scale-dependent features may change this conventional picture and boost the cosmological collider signals. In this paper, we compute cosmological correlators of the primordial curvature perturbations exchanging an intermediate heavy field with periodically varying couplings. The basic setup corresponds to inflation scenarios with globally oscillating features that enjoy a discrete shift symmetry.
